    Upvoted for adding that tier list

    It's better not to rely on that table. A lot of SATA SSDs are TLC + DRAM so they are tier 1?

    P3 uses pSLC, which does make it a bit more tricky to evaluate.

    • Table is only used for NVMe deals

      SATA SSD's are at the stage you can go by brand:

      Tier 1 - Crucial, Samsung, WD, Seagate
      Tier 2 - SanDisk, Kioxia
      Tier 3 - Silicon Power, Patriot, Team, ADATA

      • +9

        Crucial BX (QLC), MX (TLC) how is that the same tier??

        • BX is TLC without DRAM, still better than QLC

          • +1

            @xTerra: Both 1TB and 2TB of BX500 are QLC. The other BX are inferior grade TLC. The inferior grade TLC does 100MB/s after SLC cache runs out.

            That's the issue relying on cell technology. Even for TLC, there are different grades too. Furthermore, even with the same model, different batches can use different grade of NAND flash. WD, Samsung, Crucial had all done NAND swap in their popular SSD models.

      • +4

        If you looked at tier lists in most sites (i.e. LTT), they are generally done by controller.

        WD, Sandisk - same company now. With so many glue and go SSDs, this rely on brand doesn't make sense. Majority of tier 1 in your list have done NAND swap for a lot of their popular SSDs. BX500 isn't that great. MX500 apparently has DRAM reduced (in the newer batches).

        Some of the gen 4 SSDs, 2TB and 1TB versions behave differently.

      • +5

        Bad advice, most name brands still produce different tier SATA SSDs

        Tier 1 - Crucial MX500, Samsung EVO 870, WD Blue
        Tier 2 - Crucial BX500, Silicon Power A55, WD Green
        Tier 3 - Samsung QVO 870

        I don’t know if there’s any DRAM-less QLC, maybe some of the higher capacity cheap ones like the BX500
        Also I’d choose the QVO 870 over any of the options listed in Tier 2. DRAM seems to be more important with SATA than with NVMe so I’d swap Tier 2 and Tier 3 if looking at SATA drives

        • Brand snob. Better off looking into the nand controllers and reviews before purchase.

    Where does my nearly 10 year old Samsung 840 EVO 1TB 2.5" SSD fit into everyone's made up tier charts?

    • +3

      Looks to be TLC with DRAM so Tier 1?
      The tier chart is pretty rough, the controller is an important component that is not accounted for

    • +1

      Suppose to be in "tier 1", but we know that SSD has the infamous slow old data read issue and requires a firmware workaround.
      But we know what OP is going to say, the tier list is for NVMe SSDs only.

    • In some cases (like writing a large amount of data at once) it may be faster than some current QLC drives.

  • Actually pretty good deal, even considering the Plus version is $639 from scorptec.. :)
    i still don't understand why we get punished from AU wholesalers and resellers for components :|

  • Edit : I missed the Gen 4 in 1X, but you can also get QLC Gen 4 drives too.

    The table is good, but it doesn’t distinguish between the different max speeds of SATA, NVME Gen 3, and NVME Gen 4.

    E.g — this deal is for a Gen 3 TLC drive.

    • Isn’t QLC performance below Gen 3 so Gen 4 won’t make any difference?

  • How is it to use PS5? Is it compatible enough to get a good gaming experience.

    • It is not for PS5. Crucial elected to disable PCIe gen 4 support on this SSD, despite E21T is capable of supporting that.
      This SSD supports up to PCIe gen 3 only.

    If you are after an SSD tier list, it is better to check: https://linustechtips.com/topic/1092033-ssd-tier-list/

    Do note that:

    • The list now puts PCIe gen 5 x4 SSDs in tier S.
    • The list is missing newer SSDs such as 990 Pro, SN850X, NV2, P3 (this SSD) etc…

    P3 should be in tier E (budget).

  • How slow does this get on really big file writes?

    • +1

      Down to 100MBps

      Since it's pSLC, the cache size is about 1/4 of your free space.

    • +2

      It uses pSLC, so initially, it can write approximately 1TB of data at SLC speed. After that, being pSLC, it has to do recovery and re-write the data in QLC. So, if your usage pattern is that you will write 1TB max initially. Then, download new games to that SSD, then it should be all fine. Otherwise, you might want to wait for it to complete the recovery. Once fully recovered, you probably get another 700 to 500GB of pSLC. During recovery, the write speed (after pSLC is exhausted), is around 100MB/s.

      • oh that was easy to understand. thanks

      • Thanks, typically writing 2TB at a time, so I'll give it a miss.

  • The search for an affordable ps5 compatible 4tb ssd continues…

    My kidneys are staying inside me thank you.

    • +1

      same same

    • Crucial P3 Plus is meant to be PS5 compatible. QLC and DRAMless though.
