How big of a deal is this?
The 232-layer QLC 3D NAND die manufactured by YMTC (Figure 1), was found in the ZhiTai Ti600 1TB solid state drive (SSD) which was launched in July 2023 without much fanfare (Figure 2 and Figure 3). This new QLC die has the highest bit density seen in a commercially available NAND product at 19.8 Gb/mm2 https://www.techinsights.com/blog/china-does-it-again-nand-memory-market-first

Rinkles posted:How big of a deal is this? IIRC adding more layers isn't that difficult -- like, the yield is fairly linear, there's isn't some sort of diminishing return to adding layers. So there's not much yield difference between 2 100 layer chips and 1 200 layer chip. The 200 layer chip will be cheaper, but it'll also be slower in a whole-device context because all those layers share the same IO lines. So nah I wouldn't call something "the most advanced chip" just because it has the most layers. It's the most advanced in storage density and $/GB, but those are areas where these companies are constantly leapfrogging each other.

I don't know NAND that well so I'm poorly (mis)remembering things told to me or from materials I read, but there is complexity in adding layers. Basically the vertical channel they have to etch/drill down all the way to the bottom of the layers is difficult, you can't have it twist or taper too much and I'm assuming if one of the layers is bad then the whole die is lost. String stacking was kind of a hack to get around this by stacking and connecting dies and getting the subsequent layer count. Adding layers is important because that's how you increase your capacity. Micron's 6500 ION is TLC but matches Solidigm's QLC drive in size simply because of the layer advantage. In terms of QLC, I also know very little but Solidigm from what I can tell positions themselves as the QLC Champions (no one is going bigger than them or pushing QLC in the data center as much). But they've abandoned (or been forced to abandoned by Korean management) floating gate and off-hand remarks I've heard made it sound like FG couldn't really scale beyond ~200ish layers (Solidigm QLC I believe is at 192). QLC isn't incompatible on charge trap but I think people were curious as to what the hell they are going to do since their QLC endurance characteristics may take a step back if they have to move to CT (and the FG roadmap is effectively dead). A 200+ layer QLC drive is interesting from a potential density point of view but if the endurance is even worse than a typical QLC drive then probably less interesting. Typically, the high layer count/leading edge stuff when it first comes out is sold as client/consumer products as the endurance is lower and you want to flex that cost advantage of the higher layer count. Data center/enterprise typically lags in adoption as they try to work the kinks out and get the endurance up to the expected level. Micron kind of short cutted this with the ION though as they realized they could still get the endurance up to the level of QLC enterprise drives while still matching in size (and blowing away in performance) What is interesting is a Chinese NAND company matching or exceeding the layer count of the big dogs. In spite of tech bans too. I suspect many NAND company ceos wake up in cold sweats at the idea of cheap Chinese nand flooding the market WhyteRyce fucked around with this message at 21:06 on Oct 25, 2023 |

At our last layoff the tax and security implications of a thousand people keeping their laptops were deemed intractable, so we just gave each person $2K grossed up and said “maybe you would like to buy a laptop with this?” Solidgm CISO is tied up in a closet somewhere I assume.

Yeah you pretty much have it. Some of it depends on how they're building the nand stack but yeah each layer adds more challenge. Could be etch selectively on a nand stack, the electrical magic around the cell stacks, cmos challenges, etc.

Samsung is apparently planning to raise prices for NAND flash in 2024, and is telling investors that the market "has reached bottom". I don't know how that's gonna work out for them if they raise prices and other companies don't. And telling investors "it's not gonna get any worse" is a thing companies say a lot. But this may mean that the prices for the raw flash are at least not getting any cheaper. tldr: If you've been thinking of buying a high capacity drive with the best $/GB, now-ish (maybe black friday) might be the best time for it. If you're looking at the newest fastest 5th-gen drives, they're still a don't buy since they have a huge lack-of-competition premium.

Both my main 1tb nvme and my secondary 1tb SATA m.2 are nearly full and I'm looking at having to delete poo poo to download Starfield. Time to bump up to a 2tb, I'll wind up using it in my refresh I'm planning for early-mid next year anyway. Was thinking of trying a WD Black but I read they are spinning off their SSD business back to Sandisk, or something like that? I haven't been following things too closely, but is Samsung still having some difficulties? Whats the go to choice these days? My board is a relatively old Z390 platform but as I said, it'll be going into something newer soon.

WD Blacks are great quality, and it’ll still be supported even with Sandisk taking over the SSD stuff if that happens. Starfield is meh though

Maybe, but it doesn't really affect the quality of the WD drives selling right now, which is good. (The SN770 is easily what I'd point to as the best bang/buck for desktop & gaming all-purpose use.) And a spin-off won't change the warranty terms. It's not like the spin-off company will die in the next 3 years or anything. WD is probably spinning it off so some other megacorp can buy it, since their own plan to merge with Kioxa was thwarted. Klyith fucked around with this message at 21:58 on Nov 5, 2023 |

So I saw some posts in the PC Building thread about how it might be a great time to buy SSD storage, and decided to pull the trigger on some capacity upgrades I had been thinking about. I looked around for sales and bought these: WD Black SN850X 4TB PCIe Gen4 NVMe M.2 (WDS400T2X0E) Samsung 870 EVO 4TB SATA III Solid State Drive (MZ-77E4T0B/AM) But then today I read something that reminded me that the 870 EVOs were the drives having all the reliability issues. Does anyone know the current state of those issues? Or how to test for problems when I get the drive? I'm also now paranoid that the SN850X was on sale because it also has issues.

Whazzat? The only place I'm seeing this is random redditors saying drives are dying, which is like... the plural of anecdote is not data. The Samsung 980 Pro had an actual reliability issue, which was fixed via firmware. But the 870 Evo has been around forever and I think any problems have been long since found and dealt with. The drives you got are fine. But SSDs are not 100% reliable, just like anything else. Being paranoid about a drive failing means you need better backups. FrenzyTheKillbot posted:Or how to test for problems when I get the drive? Write a bunch of data to the drive, use CrystalDiskInfo to look for Media and Data Integrity errors (for the NVMe) or Uncorrectable Errors (for sata). You can occasionally check back in again once or twice a year to see if they're still doing well.

there was a bad issue with samsung drives a few months ago that was solved by simply installing a firmware update at the time. just don't buy a sandisk or seagate and you're prooobably fine

I guess there's some confirmation bias when you google "[drive] issues", there's always enough hits to make it sound like a big deal. Thanks for the reassurance.

On that note, are there any current ssds to "worry" about? Controller IC bugs are ironed out surely. Like, across the board, even poo poo cheap ones have fine controllers right, or are there still explosive designs?

down1nit posted:On that note, are there any current ssds to "worry" about? Other than the 980 Pro, not that I know of. If you have a 980 you should check that it came with the most recent firmware -- they make new drives with lastest firmware in the factory, but maybe you got a box from the back of the shelf or something. There's new gen 5 drives coming out though. Who knows which one will be the next oopsie. down1nit posted:Controller IC bugs are ironed out surely. So there's the controllers (and associated firmware) which might have bugs. Every new generation they are doing new things and trying to tweak the most performance, so there are always new bugs. poo poo cheap off-brand SSDs tend to be pretty ok w/r/t controllers -- the market is pretty standardized on a few chips made by third-party companies (phision, realtek, etc). If they're poo poo cheap they probably don't have the latest and greatest controller, they have a last-gen one that's 3 years old and it had any problems fixed long ago. But there's also the NAND. poo poo cheap off-brand SSDs may be sourcing some poo poo cheap flash. OTOH if you go with major brands -- samsung, WD, crucial, solidigm/skhynix -- they all make their own controllers and even the cheap drive probably has a "new" controller when the drive itself is a new product. Any of them, cheap or expensive, might have firmware bugs because firmware bugs don't care about price. Only way to know is wait until the drive has been on the market a year or two. But the number of oopsies per year is low, IMO it's not really worth worrying that much about. The SSD majors use their own NAND and general opinion is that this has benefits in QC and reliability.

Amazing. I only remember ocz and early samsung OEM drives with failing hardware specifically. Firmware gets patched I understand but IC design seems solid for now and there's few, if any, bargain bin controllers with explosive issues it sounds like.

Oh yeah in the wild ocz days there were numbers from a French retailer showing models of their drives being returned for one reason or another amounting to 20-50%. And then two or three years later the numbers for every manufacturer dropped to something between 1.25 and 2.5%, which is apparently fairly normal for other storage products as well. That's not failures per se, just returns. The odds are much better now.

Ironically I still have a working OCZ drive from 2011, one of the sandforce models that failed so much that they killed the company. If I found four other people like me, we could start a reddit thread about how OCZ drives are perfectly reliable and why did they ever get such a bad reputation? Talk about the anecdote-data gap! But anyways, Flipperwaldt posted:The odds are much better now.
