Spinning Rust [Still] Ain’t Dead Yet (Redux) | Chaos Lever

Spinning Rust [Still] Ain’t Dead Yet (Redux) | Chaos Lever

Spinning rust is still not dead. Despite what some all-flash evangelists want you to believe, hard drives have a lot of life left—and yes, we’re still talking about tape too. While Chris and I enjoy a week off, we’re revisiting one of our favorite topics: storage tech and the slow demise that never quite comes. Spoiler: if you thought 2028 would be the funeral for HDDs, you may want to reschedule.

In this trip down the byte-laden lane, we dig into Samsung’s monster 256TB SSD, the physics-defying logic of QLC vs. SLC flash, and why PureStorage is ready to bury HDDs... despite being wildly optimistic. And yes, there’s tape—because nothing dies on the internet or in data centers. Ever.

Grab a Slurpee, sit back, and marvel at the storage wars that never end. Because if there’s one thing you can count on in tech, it’s that someone is always wrong—especially when they say “never.”

[00:00:00.00]
Ned: Hello, you beautiful listener. Chris and I are once again on vacation this week. Wow, it's like summer or something. And I came across an article that reminded me of an episode we recorded two years ago about how spinning rust isn't dead and the legacy of different storage mediums. The article that I came across was projecting that spinning rust or hard drives were going to die out in the not too distant future, to which I laughed, and I refer you to this episode. Please enjoy. We'll be back next week with a fresh episode. Do you recall the Nictun cat dog?


[00:00:39.25]
Chris: I recall it by name.


[00:00:41.16]
Ned: Yes. Did you ever actually watch it?


[00:00:45.22]
Chris: It's possible, but I don't think so.


[00:00:49.10]
Ned: There was definitely a period of time. I don't know if it's still true of Nictuns because I'm a grown up now, he says. No one else is going to say otherwise. It seemed like everybody at Nictunes was on some psychedelic. This is the era of Rocco's Modern Life. You had Invader Zim was a thing, and you also had cat dog, which is literally just half cat, half dog, both the heads connected in the center, which really beg the question of what happens when they eat.


[00:01:31.22]
Chris: Or after.


[00:01:34.13]
Ned: Yes, that's what I was getting at. It's not quite a human centipede type scenario, but still.


[00:01:42.22]
Chris: This is a family show.


[00:01:44.22]
Ned: Is it? What family? We got a manson family? I don't know. All right. Hello, a legend human, and welcome to the Chaos Lever podcast. My name is Ned, and I'm definitely not a robot. I'm a real human person and my central processing unit is not made of metal. Just like all humans, I've evolved past that. My brain is perfectly capable of 100% recall of all of my experiences, positive and negative, especially negative, which is great. I think it's something to do with electrons. Very, very sad electrons. Really the only electrons. They're all so negative. That was the joke, Yes, I appreciate you hammering the visitors over the head with it. Visitors? Do we have visitors now?


[00:02:37.25]
Chris: I tried to say listeners and viewers at the same time, and I ended up with visitors. It's early, leave me alone.


[00:02:44.11]
Ned: At least it's a word, and you didn't combine listeners and viewers into viewers or something?


[00:02:53.03]
Chris: Lysiverse.


[00:02:54.17]
Ned: Oh, that sounds like either a disease or something that you get arrested for.


[00:03:00.18]
Chris: They need a Z-pack immediately in either case.


[00:03:04.21]
Ned: Somebody needs a Z-Pack. Maybe it's me. I don't know. I am about to be infested with all kinds of germs and viruses since today was the first-Oh, that's right, because school's back. . School's back in session, which means my little Minions have gone off to get infested with things, which they will then bring home and smear it all over the house. Love it.


[00:03:30.00]
Chris: Something to look forward to.


[00:03:31.27]
Ned: Yes. So you can expect- Previously, we had Salmonella.


[00:03:34.25]
Chris: This year, we'll have Salmonella 3D.


[00:03:39.29]
Ned: Now with smell a vision. Let's talk about some tech garbage, shall we?


[00:03:50.17]
Chris: Anything better than this? Really? He says before looking at the topic and remembering we're going to talk about hard drives.


[00:03:57.07]
Ned: I Strangely excited about this? I really want to see where you're going with the whole thing.


[00:04:07.16]
Chris: Before we go into it in-depth, I will just say that this could have been many hours longer.


[00:04:16.13]
Ned: Than the six we have planned.


[00:04:18.28]
Chris: I hope you're all sitting comfortably. Let's begin. This month saw Samsung announcing some frankly absurd upcoming SSDs. Among them, and leading the charge in absurdification, is a 256 terabyte SSD. I'll let that think in for a minute. And a PB-SSD solution that encompasses, you guessed it, petabyte-sized SSD solutions.


[00:04:58.01]
Ned: Okay.


[00:05:00.00]
Chris: We will get into the nuance of PB-SSD in a minute. But damn.


[00:05:08.04]
Ned: Damn. It almost begs the question when they say an SSD, how are they defining an SSD as opposed to a bank of separate drives that you combine together into an SSD. I guess that's probably what you're going to get into.


[00:05:23.04]
Chris: That's part of it, yeah. Just to be crystal clear, the 256 SSD is one drive, and the PB-SSD is more of a disaggregated solution of many drives mushed together.


[00:05:37.02]
Ned: I guess if you look close enough to a single drive, it's still a bunch of chips that are functionally together as a single drive. Correct.


[00:05:48.01]
Chris: That's literally how SSDs work. Yes, and we will get into that a little bit as well. Now, if you're done with the spoilers, can't they continue?


[00:05:57.04]
Ned: I suppose. Go ahead.


[00:06:00.11]
Chris: So both of these are very future-looking. Even in the enterprise, we don't have anything approaching a 256 terabyte single disk at the moment. Obviously, these are both enterprise products. Because one thing that was not addressed at the event is why a customer would want or need that storage at all, ever. The market at the moment barely has any available options for customers at 4 terabytes, let alone larger. Still, in the enterprise, this is big news, and announcements like it have led companies such as PureStorage to announce the effective end of the existence of HDDs, a. K. A. Old-style hard drives, a. K. A. Spinning rust, as soon as 2028.


[00:06:52.16]
Ned: That's cute.


[00:06:55.10]
Chris: I mean, yeah. It goes without saying that Pure might have a vested interest in saying such things since they are an all flash storage array vendor.


[00:07:07.21]
Ned: Yes.


[00:07:08.27]
Chris: Still, they were pretty dramatic about it and have been for some months. Back in May, Sean Rosemarine, VIP. Vip? Yeah, he's probably super important, but his title is VP of R&D at Pure, flat out stated, No more hard drives, meaning HDDs, will be sold after Wow.


[00:07:33.18]
Ned: Yeah, and we'll never need more than one megabyte of memory.


[00:07:39.25]
Chris: 64 Kb ought to be good enough for anybody. Or is it 640?


[00:07:43.29]
Ned: I think it was 640 Kb because the other 300 whatever was reserved for the operating system somehow. Anyway, it doesn't matter.


[00:07:53.18]
Chris: God, we're old. He didn't just say this and flit away. He actually did give some reasons. The first one was power consumption, and again, he was high on hyperbole.


[00:08:07.29]
Ned: His own supply.


[00:08:10.24]
Chris: Replacing HDDs with SSDs could, quote, reduce the power consumption by 80 or 90%. Okay.


[00:08:20.25]
Ned: All right.


[00:08:21.17]
Chris: This is one of the areas that I didn't go into it, but suffice it to say people have looked this up and no. That's not I'm not accurate. Ssds are better because there are no physical parts. Nothing has to move, sure, but it is not 80 or 90%. Sorry. The other thing he talked about was density. Ssds, he argued, were going to continue to increase their storage capacity at a geometric rate, while HDDs, constrained by physics, were going to fall behind. No questions were asked regarding why SSDs, somehow somehow existed outside of physics, but one has to assume Rosemarine would have replied to any question along those lines with something like, Bro, you know what I mean, which we don't.


[00:09:13.16]
Ned: No, I was going to say, I don't know what you mean, bro.


[00:09:19.16]
Chris: It's always so fun to just... You completely destroy somebody's argument when you call them bro.


[00:09:27.13]
Ned: Accurate.


[00:09:30.15]
Chris: So he's leading up to an interesting point. For both hard drive types, what is the upper limit in terms of their various form factors? How dense can these things actually get? Because they're not infinite. That, for SSDs or HDDs, no matter what pure would like you to believe. In fact, this is the reason that the PBSSD factor exists, because as you alluded to atop, it is not a hard drive in and of itself. It is a mechanism combining many SSDs into one coherent hole, or as described when it was announced, I want to say 18 months ago, an Nvme subsystem for disaggregated storage with greater rack efficiency for PB scale storage. Boy, do they have a way with words. But I mean, seriously, does this sound familiar at all?


[00:10:27.02]
Ned: Sounds like a storage around.


[00:10:28.01]
Chris: A brand new concept? Yeah, exactly.


[00:10:30.20]
Ned: I feel like I heard of this before. Yeah.


[00:10:33.27]
Chris: Interestingly, this is actually already how SSDs work inside the case. They're just a bunch of little self-contained hard disclets, which is a phrase that I made up, copyright pending, all masquerading as one individual disk through the power of super-duper fast internal communications and It's not a wild idea to say, We've got this communication internal to the drive, let's expand it outward, and enable you to create Basically, just get a rack, plug X amount of hard drives into it. They all are fluent in PB/sd, and now all of a sudden, you have petabytes-sized single drives. Which when you When we talk about some of the use cases that they were talking about, is obviously the future. And of course, and I weep to say it, the example use case was AI.


[00:11:40.23]
Ned: Of course it was.


[00:11:42.14]
Chris: Because what else? What else is there in the world at all? I don't even think we have lawn mowers anymore.


[00:11:50.19]
Ned: Well, I mean, they're all AI-powered lawn mowers, naturally.


[00:11:54.19]
Chris: Oh, God. I've seen the lawn mower man. That does not end well.


[00:11:58.28]
Ned: Oh, wow. I was going I'm not going to reference the happening, but Lawn Mower Man's way better as a movie and a concept.


[00:12:07.20]
Chris: This is another aspect that I didn't go into all that much is we're reaching the upper limit of how much stuff we can mash into a 2. 5-inch drive case or even a 3. 5. But my side question, and the one that I didn't go into in-depth, is why in God's name are we still using 2. 5-inch drives in the data center?


[00:12:29.07]
Ned: Well, importantly, we're not. Maybe if you've done your research, Jesus Christ, you would know that there's a new form factor that's becoming more commonly used, which is called the EDSFF, which stands for enterprise Data Center Standard Form Factor. Yes, I looked it up. It used to be called the Intel Ruler Form Factor, but then they opened it up as an industry standard. I remember the ruler? Those were so cute. They're extremely adorable, and they basically run the length of the server or the depth of the server, and they fit into a one U size space, and they're hot pluggable, which is a step up from an internal style drive. And so within that, you can pack a ton of SSD chips inside that single ruler form factor. And it was the first time that I saw, I want to say they packed a petabyte of storage, and this was many years ago, eight years ago maybe, when they packed a petabyte of storage in a one-use server using this form factor, they can pack a lot more in now, and it's all using the same bus on the back, which is the MDME bus.


[00:13:45.20]
Chris: If I remember correctly, Ruler came out seven, eight years ago. Yes. The whole idea was to revolutionize the amount of storage that was possible in a pizza box server.


[00:13:58.26]
Ned: Yeah.


[00:14:01.26]
Chris: Okay, cool. I did not see that when I looked it up, so I'm glad that it's still around.


[00:14:07.14]
Ned: Yeah, I'm trying to remember how I stumbled across this relatively recently. I think I was looking into adding some SSDs for one of my systems, and it's not a server form factor, and I kept seeing this EDSFF, E. 2, and E. 1. I was like, What is this? Will it fit in my computer? The answer was, Definitely not, and you can't afford it.


[00:14:32.25]
Chris: If you have to ask.


[00:14:35.18]
Ned: Exactly.


[00:14:37.20]
Chris: In order to understand these drives and these crazy densities that we're getting, it probably makes sense to talk about how SSDs actually work.


[00:14:51.08]
Ned: Okay.


[00:14:52.01]
Chris: Let's do that. Again, I'm going to gloss over some things. Ssds are It's built and made up of a lot of what we're just going to call cells. How does the cell work? It holds an electrical charge. I'm not getting any more deep into that. That's fair. Just stick with that model. You put in as many cells as you can, that's how much storage you got. However, SSDs have an ability to do something interesting, which is not just hold a charge, but read that charge. And this is the way that they get multiple pieces of information or a larger blob of information into a cell. These are listed out as SLC, MLC, TLC, and QLC. And then there's a PLC, but that hasn't been released on the market. What they equate to is single-level cell, multi-level cell, triple-level cell, quad-level cell, and then finally, penta-level cell. Now, obviously, when they released MLC, they did not expect any more density. If we didn't go single, double, triple, we went single, multi, triple. So that was a big oopsy. But the problem was they printed all the labels already. You understand.


[00:16:22.28]
Ned: We have all made naming decisions that we've come to regret.


[00:16:30.04]
Chris: Yeah.


[00:16:34.02]
Ned: Anyway.


[00:16:34.20]
Chris: This really is the key difference between an SSD and an HDD. This is where the pure guy was alluding to the fact that SSDs can have more data on them. For a spinning disk, I think everybody already has an understanding. There is X amount of literal physical space on a spinning platter, and there can be multiple platters per hard drive. They are physically written to by a stylus at the end of a moving arm. It's the record player model. The drive spins real fast, the arm reads the data, either that changes it, deletes it, whatever. And the faster the spinning disk can spin is the faster the drive can operate. Interestingly, and again, in things that I'm not going to go into more depth about, it is really But not as much of a difference as you would think anymore, because the biggest thing that makes drives, HDDS run faster is in fact the firmware and the way that the data is logically deployed on the spinning disks, which is one of the reasons you don't see 15,000 RPM drives anymore.


[00:17:48.28]
Ned: 7,200 RPM should be good enough for anybody. Damn it.


[00:17:55.09]
Chris: This joke is never going to get old.


[00:17:57.02]
Ned: No, never. Just like us.


[00:18:02.23]
Chris: Everything hurts. Back to SSDs, which have no moving parts, have to do it differently. They have all those cells that hold an electric charge. Now, that electric charge has to be within an acceptable range. Too low, and you can't measure it accurately, too high, and you run risks of, A, the electric charge jumping from cell to cell, which is or B, nuking the drive, which is arguably worse. But still, this is pretty creative. When you started with an SLD, remember A single... That's the mistake that I made. I keep calling it SLD, not SLC. When you started with the originals, an SLC, a single-level cell, what you What we were doing was saying, yes or no, is there a voltage in this cell? So you had a binary value of either zero or one. And like I said, the electrical charge has to be within an acceptable range, and that range varies by manufacturer. But for this example, let's just say 2 volts to 3 volts. The cell holds the charge, the cell reads the resistance, and determines, yes, no. Is there a charge? That's how an SLD works. This makes SLDs simpler to manufacture.


[00:19:38.26]
Chris: It makes reading and writing extremely fast, and it makes the cell much more stable. This is a big three things that make SLDs the best, and unfortunately, also the significantly most expensive kinds of SSDs. It also runs into the same problem as the spinning disk we talked about earlier, which is you can only cram so many cells into an SSD. So what they did to change the amount of density of the drive is change the way the cell works. Instead of it being Is there a charge or is there not a charge? They started to read the charge, which means we had an acceptable range of... Well, you can go from zero volts to three volts, right? Because obviously, off is an option. So with MLD, which is, remember, dual instead of single, it is doubled. So SLC can hold a value of zero or one. Mld LLLC can hold a value from zero, zero to one, one. So if you're counting in binary, it's zero, zero, zero, one, one, zero, one, one. It does this by changing the value of the voltage. It It's no longer a yes, no, it's a measurement. You could say, and I'm going to read them all out here, this is a lot of numbers that's going to make everybody's eyes cross, zero to one volts could mean a value of zero, zero.


[00:21:12.18]
Chris: One to 1. 65 volts could be a could be a value of 0. 1, 1. 66 to 2. 33 could be a value of 1. 0, and 2. 3 to 3 could be a value of 1. 1. Do you follow?


[00:21:28.10]
Ned: I do follow, and I don't see where you're going with this.


[00:21:31.27]
Chris: As we go from MLC to TLC to QLC, the same thing happens. The only difference is the range of voltage gets smaller. Because again, you can't go outside of the acceptable range or the drive will explode. I'm only a little bit exaggerating.


[00:21:53.08]
Ned: Fair enough.


[00:21:55.22]
Chris: By the time we get to QLD, which is the most popular consumer level of drive and the densest by far, we can now hold a value from zero, zero, zero, zero zero zero to one, one, one, one. In a cell that is the same size as one that could simply hold zero or one. It's cool, right? That's a big change in disk density.


[00:22:21.17]
Ned: Yeah, that is a big change. I'm sure it comes with some trade offs, though, which is why SLC probably still exists in the enterprise some now?


[00:22:31.29]
Chris: You are correct. Qlc is way more data dense. It is also slower to write because you're writing more to one cell and reading more from one cell and more prone to failure. Two reasons for this. First of all, as those changes in voltage get closer together, that means they have to be more precisely measured. It also means that by changing the voltage in that way, it wears out the cells faster. Think of the margin for error when your options are either on or off versus a very narrow slice of voltage. The argument is the SLC wears out at the same speed as the QLC, but because the range of acceptable value is so much wider, it lasts longer at a high performance range. Qlc, the second that that cell starts to slip, it's written off and you can't use that cell anymore because it is no longer reliable. After a certain number of these cells fail, the drive will mark itself as drive failed. This is worse the denser you get because the cell simply has to do way more work to do reads and writes, and this is inversely proportional to the data density per cell.


[00:23:57.01]
Ned: Cool. Interesting. Right.


[00:24:01.22]
Chris: So how do we measure this? Well, there's a couple of different ways to track drive failure. The one that is predictive and used in the market is called a TBW or a terabyte write. So this is effectively the expiration date for an SSD. How many times or how many terabytes of data have been written to the drive is an estimate of how long the drive can reliably function. Now, this is another game where you get into the market and you see 16,000 different hard drive options from all the hard drive vendors.


[00:24:36.09]
Ned: Right.


[00:24:37.26]
Chris: So these numbers can vary enormously. I just grabbed two different products from two different companies, or two products from two companies, so four products. Two plus two plus one plus two. One plus two plus two plus two. A Crucial P3 M. 2 SSD, which I'm sure you know what all those mean, is a QLC drive, and it is rated for 800 TBWs, whereas a Crucial T700, which is a TLC, is rated for 2,400 TBW. That is four times the reliability. Difference in price is about 30%. So it's interesting decision you have to make on that. But those are That's two different product lines. That's as close as I could get for... Those are the kinds, M. 2s are basically the drive that operates your motherboard. It's in your laptop right now.


[00:25:39.00]
Ned: Indeed.


[00:25:39.27]
Chris: If you want something more standardized, a 2. 5 form factor from a few years ago, Samsung has a series called the 800s. The 860s, the QLC version is rated for 360 TBW, and the TLC version is rated for 600 TBW. So even there, 60% difference in endurance and reliability. And if you want to go into something more enterprise at that scale for that type of drive, the pro version, which is MLC, remember, that's the duo, is rated at 1,200 TBW. As you go up in density, you go down in reliability in It's in a pretty... What's the word I'm looking for? It's pretty mappable and pretty obvious no matter what product you're using.


[00:26:39.23]
Ned: It's interesting that it's measured in rights. It seems like if you primarily perform reads on the drive, then it should, in theory, last a lot longer than a drive that has a really heavy write balance to it.


[00:26:56.29]
Chris: Yes. Not only that, if you do side side-side comparisons of these types of drives, the read speeds are not nearly as dramatically different from one another. The write speeds are where it falls off a cliff.


[00:27:10.24]
Ned: I see. If you need an extremely performant drive for doing writes, if you were putting something in, say, a database server and you wanted something for that, a heavy write disk, you would go with something like an SLC or an MLC for that. But for the long term data storage, a QLC might fine. Correct. Or maybe use a hard drive.


[00:27:34.18]
Chris: For example. And the last point I'll put in here, as we talked about at the top, an SSD drive is actually a combination of a ton of little drivelets that all masquerade as one disk. One of the things that these manufacturers do, the QLC, let's say it's a two terabyte drive. The QLC disklets will make up something like 1. 9 terabytes of that. The other part of the drive is actually used as a cache and is generally SLC. So it tries to mask some of those write speed limitations by having a super fast cache in front of it, which then the drive transfers that data into the actual disk itself in the back-end when it doesn't have to use the cache. If you're doing simple file transfers, that means that you never see the right limitations of a QLC drive. Again, this is where it falls apart in terms of the enterprise, where if you're running fast writes all the time, that cache will get filled, forcing you to write directly to the QLC and performance falls off a cliff.


[00:28:42.15]
Ned: Right.


[00:28:44.06]
Chris: Which, incidentally, if you go back in time a little bit, is exactly what we did with hybrid drives.


[00:28:51.10]
Ned: Okay, I remember those. Or fast cache. Yeah.


[00:28:57.26]
Chris: Anyway, so where does that leave us with HDDs? So HDDs have a different set of problems. The first one is they are way more sensitive to environmental concerns. They have moving parts.


[00:29:15.25]
Ned: They do.


[00:29:16.29]
Chris: You ever drop an HDD?


[00:29:20.00]
Ned: Yeah.


[00:29:20.17]
Chris: How many beats did your heart skip? Did you start writing your letter of resignation before it hit the ground or immediately after?


[00:29:30.00]
Ned: But, sadly enough, it was on the hard drive to begin with.


[00:29:32.24]
Chris: That's the thing that is much less of a concern with an SSD. You ever leave your laptop in the car in the winter?


[00:29:41.19]
Ned: Mm-hmm.


[00:29:42.14]
Chris: You had to sit there and wait for it to warm up before the hard drive would spin? These are places where SSDs not only won, but just demolished the competition.


[00:29:56.10]
Ned: Oh, yeah.


[00:29:58.00]
Chris: People of a certain age might remember that the first MP3 players had little tiny spinning disks in them.


[00:30:04.28]
Ned: They certainly did. You could feel it when you were holding the first-gen iPod, you could feel the hard drive spinning up. And I didn't have a first-gen iPod. I had a Rio something. I don't remember the exact model. Rio?


[00:30:20.29]
Chris: Was that from... Yeah.


[00:30:22.24]
Ned: But I had a Rio, and that had a... Wait, it had a 20 gig hard drive in it. Holy cow. Whoa. So So much music on that thing. But yeah, I remember when the... Was it the iPod mini came out? That was the first SSD? Or it might have been the iPod nano. I think it was the- No, the nano was after. Okay, I think it was the mini was originally small form factor hard drive, and then they switched it to an SSD in the second gen. And that was a game changer because now you didn't have to worry about what would happen if you dropped your iPod, which people did constantly.


[00:31:02.28]
Chris: I'm looking at one right now. Anyway, believe it or not, HDDs, though, do still have their benefits, and they are still valid in the data center and at home. In both cases, HDDs remain cheaper per gigabyte than their SSD cousins. In some cases, and at high density, that could be three to four times less expensive. This is one of the reasons that I have two HDDs that I use as my backup drives. Yes, plural, be responsible. One of those drives is 10 years old at this point, which does make me a little nervous. But hey, that's why you have the backup to the backup. The reality is a 256 terabyte drive is insanity. The fact is, if that drive fails, you have now Now a problem with 256 terabytes of data. A massive drive is always going to be a risk, hence why RAID was invented back in the day and why PBSSD is reinventing the wheel today. Spread the wealth and limit the blast radius when a drive fails, because it's not if, it's when.


[00:32:23.12]
Ned: Yes.


[00:32:25.23]
Chris: Entry is a thing. Get used to it.


[00:32:29.15]
Ned: Or don't. Entry doesn't care.


[00:32:35.04]
Chris: One other fun thing that we can talk about in terms of mass storage, reliable data preservation, now and into the future.


[00:32:44.03]
Ned: No, don't say it.


[00:32:46.22]
Chris: Magnetic tape, baby.


[00:32:48.08]
Ned: God, damn it.


[00:32:51.25]
Chris: Magnetic tape, even as we speak on the market today, has more capacity than any single disk drive of any type and almost infinite reliability to boot. Not actually, literally to boot, because if you try to boot off, you get the joke.


[00:33:05.29]
Ned: I get. I get things, mostly.


[00:33:08.23]
Chris: Capacity forecasts show SSDs, HDDs, and tape all continuing to expand the number of usable terabytes with tape consistently on top. Consistently. Even beyond 2028, Ned. Just this month, IBM announced a TS 1170 tape that handles 50 terabytes native at an I/O rate of 400 megabits per second, which is pretty fast.


[00:33:38.03]
Ned: Yes.


[00:33:38.20]
Chris: Like, period. It gets even better if you look at the full ecosystem because it's not just buying a tape. You have to buy a tape library, you have to buy software, etc. But if you do, you're looking at 877 terabytes native with the conservative three to one default compression leading to 2. 63 exabytes of reasonably accessible storage. Now, that's on the market right now. It's important to note, though, that even though this is an entirely new system because it's a new tape new tape, new drive, new software, all that stuff together, it is only an incremental improvement on current technology. It is an impressive leap because that 50 TB native more than doubles the storage available on previous tech and everybody's favorite, LTO9. Back in the lab, IBM has been working with Fujifilm, and they have been teasing revolutionary technology for magnetic tape that will be 10 times denser at native capacity. Wow. Holy crap. Now, they've been saying that it'll be out by 2025 for three years now, so let's be a little skeptical, but it'll definitely be out. And so will something from LTO. The LTO Ultrium roadmap has 576 terabyte native tape listed in just five more generations, which if you're keeping score at home, is approximately five years.


[00:35:12.28]
Ned: Okay.


[00:35:14.06]
Chris: So Oh, yeah. That's not going away either, whether you like it or not.


[00:35:20.18]
Ned: No. I mean, there are some obvious limitations to tape. If you're not writing and reading sequentially, it's a lot slower because it doesn't really have random access as an option.


[00:35:36.19]
Chris: No, that's the point.


[00:35:37.28]
Ned: But for things like archival of data or archive retrieval of data where you are doing just straight up reads off of a tape or just writing straight to tape, I mean, that's pretty hard to beat in terms of capacity. Right.


[00:35:55.26]
Chris: One other thing to note is that tape has has the ability to physically do write once read many, which is a pretty big deal in the whole don't get ransomware and lose all your backups argument. The way it is done on hard drives of any type is in software. So it probably works just fine. But if you really want that level of reliability, you need a physical medium. Also, fun fact, LTO has distinctive two-toned cartridges, so you can tell the difference between a worm drive and a regular tape.


[00:36:32.13]
Ned: Who's fancy? You fancy.


[00:36:35.17]
Chris: And also, tapes don't need power, ever, unless they're being written or read, which ruins the other talking point.


[00:36:45.10]
Ned: Yeah, I mean, they do need power in the sense that you need to store them in a climate-controlled area. So there is some power required, but your point is taken, they don't need to be actively powered on, though I'd argue an SSD that also doesn't need to be actively powered on to pull data. But I think the big win here is the fact that you have these enormous tape libraries with a robot that can automatically retrieve a cartridge, and the only thing that needs power is the tape drive and the robot.


[00:37:21.12]
Chris: It's a fun fact that tape makes a huge impact in companies that use things like the cloud. Because guess what backs up a lot of the stuff that's in the cloud?


[00:37:36.04]
Ned: Yeah, it's tape, isn't it?


[00:37:39.04]
Chris: To be fair, they've never officially released what goes into glacier or long term storage. But we have a heavy amount of innuendo that assumes the tape is the majority of it. But they will use whatever they think is the cheapest. And for some data that hasn't been accessed for years, that could literally mean just writing it out to a Blu-ray. That's an interesting side tangent that I also didn't go down. And then just looking future, future, future, future. There are some things that will supplant these technologies eventually. It will happen. Some of them we've talked about on this show or some other version of this show. These include things like DNA-based data storage, quantum memory, and of course, 5D optical data to storage, a. K. A. The Superman memory crystal. All these are extremely pie in the sky at the moment, but if the history of it tells us anything, it's that one of these things will make a massive breakthrough and become mainstream far sooner than we think. But it's still not going to be like next week. The reality is the hard disk landscape is the same as it ever was. Ssds for portable devices in first-line storage, HDDs for second-line or less performant storage, and tape for archival.


[00:39:04.01]
Chris: That is not changing anytime soon, and certainly not by 2028.


[00:39:11.20]
Ned: I'm sure that that VP you mentioned earlier has a bit of a myopic view of the storage world, especially given the company that he works for, and it is in his best interest to talk about how hard drives are dead. Somebody else who has a tendency to be occasionally wrong who may have said that tape is dead about five years ago, and they were very wrong, and it was not me.


[00:39:37.14]
Chris: We still have the tapes, Ned.


[00:39:40.01]
Ned: We are currently on magnetic tape. Ironically, true. Oh, I feel that deep in my heart somewhere. Yeah, so I think it's interesting to see how the storage market is today and how the storage form factors that we have. None of them have really gone away, but it's not like every storage form factor is forever. I submit to you the humble ZipDrive. Ahead of its time, but certainly not used by anyone anymore, except for probably some random nuclear silo that started using it in the 1990s.


[00:40:17.11]
Chris: That was the big improvement over the ENIAC.


[00:40:23.17]
Ned: The eight-inch floppy or 12-inch floppy that they were using. They're like, We upgraded to zip drives.


[00:40:29.17]
Chris: We're doing it.


[00:40:31.26]
Ned: Oh, hell. All right. Well, hey, thanks for listening or something. I guess you found it worthwhile enough if you made it all the way to the end. So congratulations to you, friend. You accomplished something today. Now, attune yourself to the universal vibration of all things and become one with the Cosmos. Or go buy a slurpy. It's the same thing. Yeah.

[00:41:10.10]
Chris: Did you ever do the thing where you just hung out behind the 711 because you were the coolest kid on Earth?


[00:41:15.29]
Ned: We hung out in front of the 711 because we were rebels.


[00:41:19.27]
Chris: Wow. Or you were scared of the dark.


[00:41:23.06]
Ned: Shut.
