  Japanese reviewer indicates this is a 176 layer QLC drive https://i.imgur.com/gziV0VI.png

  There is a Crucial P3 Gen3 4TB Dramless QLC for just a few dollars extra ($264.77) from Computer Alliance ebay store, if you prefer Crucial & buying locally (5 yr warranty)

      Doesn't really matter if the NAND is trash-tier QLC, which is slow at the best of times.

        There's a bit more to it. Reads are still decent. Writes - that's the main issue. With aggressive SLC cache, if you avoid large writes and have sufficient time gap between writes, then you could avoid the ugly side of QLC. Problem is when you cannot, the folding write penalty while writing more data is amplified and really bad / slow.

  Silicon Power drives are garbage

  They list the drive endurance TBW in a PDF file because they swap components so regularly

  The UD90 is listed at 2400 TBW endurance and uses Crucial's/Micron's own 176L QLC NAND as mentioned by scrimshaw

  The equivalent Crucial P3 Plus has an 800 TBW endurance

  Do you believe Silicon Power has extracted triple the endurance from the very same NAND that Crucial produces and uses for their own drives?

    It's well recognised that even for QLC, most NAND will last way belong their TBW rating with decent wear leveling. TBW arguably still has some very loose correlation to how long the NAND will last, but is much more related to how much the company wants to spend on warranty claims with probably marketing and not wanting their consumer drives to be seen as competing with their enterprise drives as additional factors. Will 800 vs 2400 is a bit extreme, it's very common to see ~2x difference between TBW for the exact same NAND from reputable brands

  • 

    [Deactivated] on 02/08/2023 - 18:13

    Even 800 TBW is good enough if someone using this for game/storage and normal use drive. Bust still despite all the +ve comments SP drives receive on amazon, am a bit scared to buy one.

    Silicon Power drives… if you managed to get early batches before the swaps at a good price, they are probably okay. However, nowadays, with prices falling like crazy, Silicon Power does lead the pack (in a bad way) in terms of swapping for cheaper parts. I too found the 4TB TBW questionable since it is now QLC. However, technically, such TBW "could" still be achieved by having more spare cells. I doubt Silicon Power puts in way more spare cells to achieve that TBW. It's most likely Silicon Power forgot to update it.

    Realistically though, TBW is mostly an excuse for SSD makers to deny warranty. Considering the 990 Pro infamous SSD health sharp drop issue, do most people write data like crazy on SSDs with high TBW?

    Why bother with SATA anymore unless you're keeping an old machine going?

      Mini-iTX have limited M2 slots - sometimes SATA is all you have for expansion

        2 slots, 4 TB each. 8 TB, why sata? Just sell the old lower capcity nvme if you already have some or use them as external drives with enclosures.

          need to upgrade my 2 sata slots too

    • 

      furythree on 02/08/2023 - 20:09

      because i have an itx with maxxed out slots already

      and cheap nvme to sata adapters are expensive

      i have exactly enough room to fit 2 2.5" sata SSDs perfectly and dont need the performance since its idle storage and at most game boot drive where i wont really notice the difference much

      premium AAA games that i play everyday are alrady on main NVME

      otherwise getting NVMEs for that purpose would be like buying 4 lambos to go grocery shopping with when a toyota86 wouldve been fine

  I don't understand all the nerdy comments.

  Is this drive good for PS5?

  • 

    lachlantula on 02/08/2023 - 18:52

    it works, but it doesnt meet the recommended speeds. you'll need a heatsink too i believe.

    You can use it for PS5.

    Tech version:

    It is difficult to evaluate the SSD properly because Silicon Power changes what's inside the drive between batches. Often, a price drop on a particular Silicon Power SSD indicates the new batch changed something (cheap out / use inferior parts).

    Based on the latest review from a Japanese buyer (Phison E21 with Micron QLC), this SSD feels like Silicon Power's equivalent of Crucial P3 Plus (but if so, we'd rather P3 Plus).

    Non-Tech version:

    This SSD is essentially in the same class as the record $229 4TB PNY QLC NVMe PCIe gen 4 x4 SSD a lot of us missed out. PS5 lets you use them despite these SSDs are under spec. If you won't be transferring games from external USB 3.2 gen 2 SSD to this SSD in PS5 a lot, it is mostly fine. If a few odd games don't work later on, leave them on PS5's internal SSD.

    Hard core OZBer version:

    Wait for $229 or better deal.

      DnA-bargain on 02/08/2023 - 22:50

      Thanks for the explanation.

      I will wait for a $229 or better!

      Question - I bought a Synology 923+. Will this SSD or the Samsung 980 Pro (without heatsink) be good or do I need a heatsink for the Synology too?

      •

        +1

        There is no official spec on 923+'s m.2 NVMe slots. Based on limited number of reviews, it appears to be PCIe gen 3 x1. That makes sense as I think it supports up to 10Gbits ethernet (so 1GB/s NVMe is sufficient). I don't think a heatsink is needed. Do bear in mind a lot of SSDs are only able to be used as a cache drive. Guessing Synlology wants you to buy their SSDs if you want to use SSDs as storage.

          @netsurfer: I bought 2x 2tb 980 pros last time it was on amazon US.

          4tb now. Without a heatsink.

          Sitting on my desk.

          I have a PS5 and I have a Synology. Otherwise use Macbook.
          What should I do with these?

          And I really appreciate your answers!

            @DnA-bargain: Since you have them, might as well use them. Put 1 in PS5 and 1 in the Synology NAS. Unless you have some needs to have a 2TB external SSD for your Macbook, but you probably want to get a Thunderbolt 3 or 4 enclosure which costs around $100 when discounted.

    btw, just curious , why PS5 needs a gen4 ssd specifically ? I play PC games from a NAS with GBE, takes a bit to load but works well.

      PS5 needs PCIe gen 4 x4 SSD because:

      • Developers told Sony for PS5, they want an SSD.
      • Mobile devices (smartphones) use flash storage so it doesn't make sense a current gen console doesn't have one.
      • The internal SSD used by PS5 goes through a dedicated core in PS5's APU which has PCIe gen 4 x4 like capabilities. Technically, it supports 6 priority levels (compared to NVMe's 2 level, thus on the safe side, PCIe gen 4 x4 is needed).
      • The APU made by AMD has CPU cores supporting PCIe gen 4 (so might as well use it).
      • There are some slow PCIe gen 3 SSDs (SSDs with SD card grade flash), blacklisting them is a pain and consumer unfriendly. (That said, Microsoft's nasty Series S|X requirement on only accepting SSDs in its tiny short list is very annoying (zero PCIe gen 4 x4 SSD is in that list and the ones on the list aren't even the best PCIe gen 3 x4 SSDs) forcing people to buy Microsoft branded expansion).
      • Marketing (Microsoft went with PCIe gen 3 SSD then did a marketing spin to claim PCIe gen 4 x2 - same bandwidth as PCIe gen 3 x4).

      Ratchet and Clank PC version uses DirectStorage and a proper PCIe gen 3 x4 is recommended.

  I see people bagging certain SSD's but is an average person actually going to notice a significant difference in real life usage or is this all just based around pointless benchmark testing comparisons?

  I'm not denying that there are better and more expensive options out there but if someone wants to just use it for PS5 storage or expand their PC storage with some performance benefits, surely something like this is still a good value rather than forking out more money for something else?

    As mentioned on the 2TB deal

    Kingston NV2 and Silicon Power drives are only for storing data you have no issues with losing eg. PS5 expansion, games library, temp storage

    These garbage drives definitely have their uses so if you feel the price is right, roll the dice

    This one is a bit tricky since it is QLC. Being 4TB, it is quite likely you won't notice its weakness initially (unless you fill it up to 70% in one go from a PC). However, once the SSD is filled above 80%, it is likely the write performance issue becomes noticeable (since dynamic SLC cache is either not available or tiny).

    Swapping of components makes it difficult to evaluate this SSD. Part of the problem is we have seen some heavy discount on TLC SSDs. Cheapest TLC SSD (albeit low end PCIe gen 3 x4) is $109 for 2TB. When you double that, it is still below this SSD. So, that means the controller, Phison E21 needs to justify the cost. But then, E21 with TLC NAND is a better combination. Unless you really need a 4TB SSD right now, it is hard to consider this a bargain. Furthermore, earlier this year, a similar SSD (4TB Phison E21, QLC) was on special for $229. It's just hard to get excited a similar SSD is now more expensive.

      I personally got the XS70 2tb model for PS5. It cost me $153 with no need to spend additional money for a heatsink so I'm happy with that.
      In terms of reliability, I guess that's for me to experience going forward.
