    Hmm, I'm waiting for this to come in at less than double the price of the 2Tb from last month https://www.ozbargain.com.au/node/786784

    $185 would do the trick.

        Yes. However my wish for pricing on a 4Tb drive persists - doesn't have to be 'better'.

        • bcYield on 05/08/2023 - 01:56

          Most people wish 4TB for under $250.

          But yes if you have 10%-15% GCs to bring this down to sub $200.

      Not sure why people are negging your comment. Perhaps they didn't know SP has swapped the NAND to QLC on this one.

      The SSD prices need to be re-evaluated quite quickly since SSD prices are dropping still. $208.74 is technically the lowest 4TB QLC SSD we've seen on OZB so far. However, cheapest 2TB TLC price is around the same ballpark (in terms of $/GB) so this still feels a bit like paying for PCIe gen 4 x4 premium. $185 for 4TB QLC seems more reasonable for a 4TB QLC SSD from a consumer's point of view.

      It comes down to how bad you want a 4TB SSD right now. AUD isn't strong at the moment and that price on Amazon JP is currency exchange rate dependent.

  • dualcore on 05/08/2023 - 01:55

    QLC?

  • Sycotek on 05/08/2023 - 02:17

    https://www.silicon-power.com/support/lang/big5/TBW.pdf

    SP website says 2400 TBW which would make it TLC for the UD90.

    Amazon review they seem to think its QLC

    Toms Hardware has it as 176-Layer Micron TLC (B47R)

    • reactor-au on 05/08/2023 - 02:20

      Could be both, sometimes SSD makers switch up the nand and or controller.
      SP have done this with older drives so I bet they still do this sometimes.

      • bcYield on 05/08/2023 - 02:32

        Someone just reported it being swapped TLC -> QLC

        As long as it's 2400 TBW and 5 years, it wouldn't really matter to me

        • BargainKen on 05/08/2023 - 09:50

          Its not just the reduced endurance to worry about as that can be covered by warranty, its the performance hit when the cache runs out and you're now writing to the QLC NAND, it becomes much slower, think mechanical hard drives from 10 years ago…

          • bcYield on 06/08/2023 - 02:28

            @BargainKen: Same as TLC also use caching strategy? so say the speed drops 10 times becoming 480MB/s which is still 5 times faster than HHDs

              @bcYield: My QLC NVME SSD drops to sub100MBs on the raw NAND, I can tell you its not good.

              • bcYield on 06/08/2023 - 10:33

                @BargainKen: too bad what SSD is that and like at what capacity?

                  @bcYield: Crucial P1 1TB with DRAM etc. As soon as cache exhausts, not fun to look at. For me when I noticed the slowdown in a large file copy operation, but in Flight Sim when I had to reset the Map Cache file which was about 50GB, started off nice and fast ETA 5mins, ended up taking over 30mins. Didn't realise what the issue was at first till the penny dropped…Even in gaming scenarios these QLC drives can be an issue from time to time.

    • netsurfer on 05/08/2023 - 08:10

      Please assume you will be getting the QLC version of this SSD. That also means most reviews you read on the Web are no longer applicable to the current batch of UD90 4TB. Also, the quoted TBW is iffy at best. Best to also assume that wrong except for warranty claim purposes, TBW is not going to be an excuse SP (through Amazon AU -> Amazon JP) use to decline warranty.

      Silicon Power has done so many component swaps lately and that included SP's flagship model XS70. It's annoying because the new batches are clearly inferior in performance and if you read the reviews for older batches, you get tricked into thinking they are bargains.

        Can you explain why you're asking this question? People always ask if ssds are good for a specific product. Are you worried it doesn't fit? Are you thinking it's somehow not compatible? Most of the time no one will answer you because no one has that very specific same product you do

  • corgi-runner on 05/08/2023 - 07:20

    To buy or not to buy?! That is the question

    • digitalaxon on 05/08/2023 - 07:40
      +1

      I'd say skip it due to the 'gray'ness it being QLC or TLC - checked the comments and one person who bought one last month ran the phison flash id tool, and it shows Micron 176L(N48R) QLC flash memory.

      Could the app be making an error? Possibly, could SP be running magic code to extend QLC to have the same durability as TLC? Doubtful… Do you want to play russian roulette with your data? Then this drive is for you!

      Also page makes zero mention of warranty (a red flag although the warranty is well documented elsewhere) and in the US Amazon reviews for this product one of the commenters headings is '2 TB version comes with QLC flash - write speed suffer from slower NAND' - and they mention the 1tb version comes with TLC…

      • bcYield on 05/08/2023 - 07:51

        It does mention 5 years in Chinese/Japanese in one of the pictures. Look for the big 5. At this price point, well can't really expect more. This cheap for now is most likely only because stock from Amazon JP. Cuz JP is close to Taiwan?

        • digitalaxon on 05/08/2023 - 08:21

          My bad - I just did a search for the word warranty on the page.

          At this price point I guess as a mainly read only drive it might be a good cheap option, but I try to avoid cheap (not worth the headaches)

        • netsurfer on 05/08/2023 - 08:46

          It's cheap because it is now QLC. That basically means the SSD now has roughly 50% less NAND blocks so there is cost saving.

          • digitalaxon on 05/08/2023 - 10:26

            @netsurfer: As QLC stores 4 bits per cell vs 3 bits per cell in TLC assuming we are doing that comparison I believe its 25% less nand blocks needed for the same capacity.

            Given the lower durability and performance (once pSLC is exhausted) I'd pay the extra for better durability and performance.

            • netsurfer on 05/08/2023 - 19:51

              @digitalaxon: QLC, it's hard to evaluate at the moment. Reads seem okay, writes… questionable. Reliability, it is hard to tell.

              3D NAND setup is required for TLC to be reliable enough so it isn't TLC is that great. I used to own Samsung 840 so I have first hand experience of TLC gone pear shaped.

          • DmytroP on 05/08/2023 - 11:53

            @netsurfer: I think the difference in NAND blocks is not as large, QLC encodes 4 bits per cell vs 3 bits for TLC, so requires 3/4 amount of cells (so -25% cells from TLC to QLC) at the cost of 2x worse signal-to-noise ratio (so much worse reliability / TWB / speed etc).

            For me in most cases, it's a poor compromise, not very significant cost saving for a very significant quality degradation. I hope we will not going to see a transition to 5 bits per cell any time soon.

            But price wise, this looks like a reasonably good deal.

            • netsurfer on 06/08/2023 - 13:00

              @DmytroP: I read an article online, it indicates QLC provides 33.333% more storage (1 extra bit on existing 3 bits) for the same number of cells.

              Part of the problems is most reviews show flagship TLC's write performance is mostly its best situation. QLC is very common in SD cards and USB flash drives.

              • DmytroP on 06/08/2023 - 16:39

                @netsurfer: I guess so -25% cells from TLC to QLC is the same as 33.3% more storage when switching to QLC (QLC had to read/separate 16 levels of charge, compared to 8 levels for TLC to encode 4 or 3 bits).

                I agree, the practice to switch to lower end parts after reviews should be shamed.

      • Clear on 05/08/2023 - 08:00
        +1

        The 1TB in later batches now uses the same QLC flash. The smaller capacities are still likely to be TLC.

        Given its using HMB it's not the worst QLC drive out there. Plenty fine for game storage.

      • netsurfer on 05/08/2023 - 08:25

        Could the app be making an error?

        Very unlikely. Furthermore, as I have pointed out, XS70, SP's flagship SSD has recently also had multiple swaps. 2TB version had both controller and NAND swaps, 4TB version had the NAND swap. Both were swapped to previous gen YMTC NAND (which is annoying, should have been at least the current gen). If SP had zero issue swapping their flagship SSD components, do you really expect them putting in "better" TLC NAND in the mid range SSDs?

        Better NAND in mid range series AND a price drop is wishful thinking. Before you buy, ensure you are happy getting a QLC SSD from Silicon Power. Due to the component swap, at best, it will perform like a Crucial P3 Plus (but it is better to assume it will perform slightly worse than P3 Plus).

        summary
        qlc - quad layer, stores more data in less space, less durability because it takes more cycles to read / write. good for storage / archival / game drive. not good for lot of i/o applications such as video editing or so. (qlc will eventually replace tlc which is the norm these days)

      You need to contact Amazon AU. Amazon AU, for the time being, appears to offer refund (but you need to return the faulty SSD to Amazon AU). There is no guarantee that will remain like that for 5 years.

  • neosin on 05/08/2023 - 14:56

    Found this on reddit and not looking good!

    "I have a ud90 2tb that came as qlc and the drive has slowed down considerably after 600gb was filled. I would go with the mp34 for that dram."

    https://www.reddit.com/r/buildapcsales/comments/145ja0g/ssd_…

    i wonder how bad it actually is "actual numbers" and if it would slow down the ps5…

    • Wicko on 05/08/2023 - 15:16

      This is just for writing though, for a games drive when are you ever going to fill 600gb all at once? If you're doing production workloads then this is garbage, but for a games drive this is perfect.

      • neosin on 06/08/2023 - 16:49

        I think the writer meant after he put 600gb of stuff on his drive and not 600gb transfer at one go.

        No one would write 600gb of data in 1 go unless you are cloning a drive

    • netsurfer on 05/08/2023 - 20:32

      PS5's internal SSD is not big enough to cause UD90 4TB to run out of SLC cache initially. The same cannot be said for the 2TB version. You could run into QLC + folding write with the 2TB version.

      However, if after the initial transfer, you happened to have an external USB 3.2 gen 2 SSD also connected to PS5 and commence transferring games from that SSD to UD90 right after you finished PS5 internal transfer to UD90, you can and will feel the pain. The pSLC cache diminishes as the UD90 is filled.

      On the other hand, if you only fill UD90 afterwards with game downloads through NBN or from a portable HDD, the the bottleneck is more likely to be the source, rather than UD90. The worst case is hopefully UD90's write speed is at the same level as a portable HDD. Without filling up UD90 to 80% and run tests, it is hard to tell.

      In short, it should be fine for most people.
