Edit 24/11 - price drop

All time low
Single sided PCB and low real world temps so good for laptops
Custom WD controller optimised for DRAM-less design

Best choice for mid-level performance as Kingston NV2 has some serious issues and can no longer be recommended unless it is $50/TB

' See netsurfer's comments on the Kingston NV2 1TB here and here

' Digging deeper, Kingston has silently changed the controller on the NV2 resulting in poorer speeds and 50% speed drops when the drive is half full

' The most recent review confirms the silent controller change. NAND change is unconfirmed but at this point, not worth risking the parts lottery BS

  How does dram affect the performance of the nvme? I keep on hearing negative stuff about dramless but is it that big of an issue?

    Different drive (NV2 1TB) but same concept

    If you regularly write (save) large GB size files such as videos or file blobs, drives without DRAM will slow down once their buffers and cache run out

    In the graph, you can see the drive starts writing at 1900 MB/s, then throttles down to 700 MB/s and finally baselines to 250 MB/s, almost a 90% speed decrease

    In real world usage, this is where you see the Windows time estimate for the file save or file copy keep increasing because the longer it runs, the slower it gets

    We are getting to the point where you probably won't feel much difference in day to day use, unless you are frequently moving a couple hundred gigs.

    But in general.

    Dram > Dramless
    TLC > QLC

    TLC can get away being Dramless. Not sure if there are any on the market thats QLC and Dramless, if there are avoid like the plague.

      Isnt P2 QLC and dramless?

        P2 is a tricky one the old ones is dramless TLC, the newer ones is QLC, but not sure if they put in dram or not. Eitherway avoid any company that make silent changes.

          @annarchon: So I should avoid all of crucial? I heard the p5 and p5 plus lineup is pretty good

  TLC + DRAM = main system drive, PS5 expansion drive
  TLC + no DRAM = main system drive for "normal everyday users"
  QLC + DRAM = secondary storage, could be main system drive in a very cheap build
  QLC + no DRAM = secondary bulk storage only, like this

  There are no brands to completely avoid (maybe Silicon Power) and every drive needs to be considered on their spec and reviews
