Two different WD_Black SSDs on sale with both the original Gen3 SN750 and the newer Gen4 SN750 SE. I've included a comparison between the two SSDs in the table below. The SN750 is using TLC flash, while the SN750 SE is suspected of using TLC flash as well but I've been unable to confirm.

In regards to PS5 compatibility, Digital Foundry did a test on the SN750 SE since it's Gen4 and found that it does work. You can see the results here.

          Well.. I didn't say it didn't.

          Reviews I've seen show dropped frames and slowdowns etc. So I guess it's up to the prospective buyer to do their own research based on their respective end use.

          FPS and sims, probably not ideal and will result in noticeable slowdowns.

          RTS / platformers, maybe ok.

          Mileage may vary.

            @MisterTree: Seems to be a few comments around Ratchet and Clank.. I mean, PS5 wise, is that a very intense game to run?

            I'm asking as
            a) I don't have a PS5 due to the obvious shortage - and unwilling to pay a scalper for the privilege to own one.

            and

            b) How does that game rate compared to other games in complexity / speed?

            Some of the test reviews I've seen of M.2 SSDs on PS5 were showing clear texture issues, slowdowns, dropped frames etc.. and these were faster Gen 4 SSDs.

            https://nascompares.com/2021/08/03/recommended-ps5-compatibi…

            I've been using this site as a bit of a comparison too.

              @Revrnd: Rift Apart is probably the most intense game on the PS5 for the SSD so far because they do that portal gimmick where they load an entire stage from storage as quickly as they can instead of just preloading it in RAM to show off the new SSD, and for no other reason.

                @Lief: Interesting, I was just reading https://www.playstation.com/en-au/editorial/this-month-on-pl…

                Looks rather intense, definitely great use of the I/O on M.2 NVMe SSDs. Guess this is one area where read speeds really come into play.

                Some great tech that appears to have been implemented on PS5 (and XSX), Guessing that with high I/O, decompression hardware and an engine that can take advantage of those, that'd help developers squeeze every bit of speed out of the hardware they have.

                Helps that the platform they're working on is standardised and they don't have to factor in a multitude of other things (ie. different architecture, CPU configs, SSD speeds and RAM capacities etc).

                • Agret on 25/09/2021 - 22:02

                  @Revrnd: The same technology will be built into Windows 10/11 named DirectStorage, I assume developers on Windows store will be able to set a minimum device speed as a system/storage requirement.

                  @Revrnd: At the moment, PS5 games are not using all 6 priority channels the custom SSD core is capable of. It doesn't appear that Sony first party will be using them soon either. We are looking at Horizon Forbidden West being cross gen title and GOW Ragnarok doesn't quite look like true next gen yet.

                  So, as a stop gap, this could be okay. By the time it is really too slow, then SSDs should be cheaper (because by then Gen 5 SSDs would appear on the market). It will also be interesting to see the SSDs which just passes the 5500 MB/s mark will be able to cope. The internal storage of PS5 could still be used if required. It's really doubtful every first party PS5 game will push the SSD to the limit. Coding a game to utilise all 6 priority channels won't be simple. A lot of complexity and I doubt that type of complexity will help PS5 achieve much better framerate.

                  I am still cynical about games capable of taking full advantage of sequential read. With games moving to more open world, there will be more random elements. With Series X using PCIe gen 4 x2 SSD (which has the same bandwidth as gen 3 x4 SSD), I doubt 3rd party developers will really push for PCIe gen 4 x4 even if Microsoft's DirectStorage is used.

                  What WD basically did was use a 3rd party gen 4 NVMe SSD controller (a cost effective one) which supports DRAMless setup to allow WD to further save cost.

      • [Deactivated] on 25/09/2021 - 22:40

        Hmmm, this make me think what kind of games is so demanding on disks? I happen to have SN750 and it is actually better than I expected. The reading can get to 3000MB/s and the writing can maintain at ~800MB/s after continuous writing to the disk exhausted all means of caches.

    • Revrnd on 25/09/2021 - 19:35

      On a platformer it looked.. Throw it at an FPS or a sim like GT7 (when released) and you might get a totally different experience.

      Noting they said it's "fine" as opposed to "ideal". food for thought.

      • netsurfer on 25/09/2021 - 22:49

        FPS - that would have more random elements. I found it hard to imagine FPS using 6 priority channels on the PS5 and banking on SSD speed instead of memory. Let's also not forget PS5's read speed test result appears quite odd at the moment, especially for slower PCIe gen 4 SSDs. GT7, I doubt it will be 4K/120Hz. If it is going to be 4K/60Hz, and ray tracing is going to be tough on the GPU, are we 100% sure GT7 will be true 4K, rather than Checkerboard 4K?

        Richard @DF pointed out PS5 reported this supposedly 3600MB/s as 5173MB/s by PS5 for read. A number of gen 4 SSD which are quoted below 5500 are being reported as just above 5500 by PS5. So, are those safe?

    • Danthemanz on 25/09/2021 - 21:27

      Peak read/write is rarely the bottleneck in an ssd. Given the gen4 model is dram-less, I’d suspect it’s a much worse general performer.
      Haven’t done up to date research on this particular model though.

      • Edamamme on 25/09/2021 - 22:41

      Yeah, it's useful in computers with lane limited m.2. slots.
      Sometimes laptops and other junk will cheap out and give you a secondary m.2 drive at 2x speeds, with this that'll probably still be enough for full bandwidth but if it can only negotiate a PCIe 3.0 signal, it'd be limited to 2GB/sec

    Could anyone explain why the endurance TBW is so low on these, recently purchased the PNY 2TB with 3600TBW and wondering why everything else won't last as long.

    • ATangk on 25/09/2021 - 20:44

      A larger drive will typically have a larger TBW.

      Also, maybe its because of chia mining? Did you get the PNY XLR8 CS3030? For the 2TB: 5 years or 660 TBW, down from 3,115 TBW (79% reduction)

    • [Deactivated] on 25/09/2021 - 22:32

      I'm not sure whether if it was WD a little bit too conservative about their flash chip P/E counts. I would expect TLC chips to have P/E counts around 1000. So for SN750, based on TBW, the P/E count is only 600 which is might just be some kind of over provision to make sure 99.9999% of drives can actually deliver that much. For FireCuda, the number is 1300, maybe Seagate choose better chips and thus can deliver better result of they were simply bluffing as most people will never reach that much writing. Just took a look at my primary drive, for over 2 years, I merely wrote just over 13TB to it and I most likely write to the disk more than ordinary users, however, I don't use it to download stuffs. So I feel it is pretty safe to bluff on TBW as for most of the people, they won't make it close to a fragment of the promised amount anyway. If someone indeed manage to get to it, associated RMA cost is still very low in comparison the benefit it may get through it.

    • netsurfer on 26/09/2021 - 00:49

      You cannot compare endurance of 1TB SSD against a 2TB SSD. You expect a 2TB SSD to have 2X that figure to be "on par" with 1TB.

      That figure can often be affected by competition. WD and Samsung currently underquote those and honestly, it is doubtful they will hold that against you if you exceeded that when the SSD failed.

      I wouldn't get too excited about CS3040's quotes endurance. In fact, I would save the PDF which shows that now. PNY slashed CS3030 to subpar level and CS3140 (which is the successor of 3040 has a big drop in endurance). So PNY could release a new batch of 3040 with inferior NAND and slashes the endurance. The reason is most consumers don't really care about that. Also, I doubt PNY's warranty is better than Samsung's.

      No need to pick on SN750 SE just to feel good about PNY 3040.

      • AlienC on 26/09/2021 - 01:18

        Don't worry hopefully one of the big tech reviewers will do a proper updated new analysis on the endurance and longevity of the current state of nvme vs sata ssd performance so we can really know how long and how much these drives can last under a multitude of arrangements.

        The best endurance testing I know was done by either anandtech or tom's hardware and at the time samsung drives were the best or endured the most beating but that was under extreme performance.

        For longevity obviously we need time which we can't speed up unless somebody has a time portal hehe 😂😂😊🤣

        • netsurfer on 26/09/2021 - 22:30

          Endurance, honestly, is overhyped. I had 3 dead SSDs so far, 1 from Samsung, another one used Samsung based NAND. The Samsung branded one didn't even last 1 year, it was hardly used, I think it had less than 2TB total writes.

          Furthermore, some OZBers are not happy that one certain disk monitor app mark down SSD health level based on NAND wear level. So, if the wear level is over 50% and that app says your SSD health is technically 50%, are you willing to change the SSD?

          Honestly, the reason endurance is mentioned here is probably because OP of this discussion thread owns that PNY SSD. It's unusual that PNY has a really high quoted endurance rating. Considered PNY recently did a dodgy brother and started dropping the endurance rating of some of their SSDs to a subpar level (supposedly for newer batch, but the problem is they changed the official table so if you have an older batch, have you got the old endurance rating in black and white)?

          Depending on those review sites, relying on specs. Honestly, if you filled your SSD to 95%, don't expect great endurance result since there are so few free cells for the controller to swap around.

          Most reviewers won't do endurance tests. Even if some do, they won't do them a lot as that basically involves writing to the SSDs until they stopped working.

          • takemymoney on 29/09/2021 - 09:45

            @FabMan: Yes, it's sort of. Because Sony went down the shared gddr memory path, ps5 don't have a lot of standard memory so the pathway to put data in the video card is via ssd instead of ssd->memory>gpu. In terms of arch this is fine, but then devs are used to the previous paradigm so they need to adapt the code since they are used to the faster memory>GPU instead of ssd->GPU. This is clearly simplified, but mostly, the architecture changes always introduce this kind of things. It is the same thing in the PS4 - it was not until late that things started flying because until the tooling reach the masses, only few devs know the stone path.
