    Swapped out parts?

      Western Digital quietly changed the NAND flash in one of its budget SSDs with a lower-grade version that only performs as well as that of its cheaper brother.

      The change was noticed by Chinese news site Expreview, who noticed that Western Digital swapped the NAND on the SN550 Blue SSD for a slightly lower-grade version that doesn't perform nearly as well when you need to copy large files around.

      Both the old and the new version achieve write speeds in excess of 2,000 megabytes per second as long as the transfer doesn't exceed the 12-gigabyte SLC cache. However, once that is filled and the SSD starts writing without it, the speed drops from 610 megabytes per second on the old drive to just 390 megabytes per second on the new one.

      As noted by Expreview, the performance results of the new SN550 Blue drive are more in line with the cheaper SN350 Green. To be fair, this issue only becomes noticeable if you happen to move large files very often,

        Makes you want to stick with Samsung because they do update their model codes when they component swap. Even their DRAMless models offer high pSLC cache and good performance when exhausted.

      During the chip shortage they had replaced some of the good quality parts for inferior quality parts….I am not sure but I think it's the controller

    To all, please be aware of potential nand changes:

    "Silent changes to Western Digital’s budget SSD may lower speeds by up to 50%"


  • Yes there is a chance that might receive a newer version with swapped out parts:

  • see also the last deal where some have received the drives and they were the old gen.

    I think they mean old compared to the new SN 570

  • playing Russian Roulette with SSD's


    if you're OK with DRAMless (which you are if you're looking at this post) then wait for another eBay sale and pick up Samsung 980. at least we know it hasn't been compromised yet!

    WD swapped out the TLC with QLC in the SN550 (old gen in the listing), then releases a brand new TLC equipped SN570 (new gen in the listing). Completely forgetting to let people know that they have done the swap around with the SN550

      Lol forgetting…. Just slipped their mind I'm sure

        lol, reminiscent of their forgetfulness in informing people purchasing WD Red drives for NAS use, that they were actually SMR drives and not entirely suitable for quite a few NAS applications.

        • Haha yes not their first forgetful moment… They need to get tested for dementia at this rate
