Samsung 870EVO (SSD), 980 Pro/990 Pro (NVMe) are all TLC drives. Kingston KC3000 is faster than 980 Pro, hence it's probably TLC, too.

A decent rule of thumb if that if a drive uses TLC, it will probably say so in the spec sheet.

If it's left ambiguous then it's either QLC, or a lottery where the "same" model may be TLC or QLC.

    Kingston NV2 is in that "what you get may differ" category, and Kingston explicitly says that what you get may change. I have two NV2s with differing die count, for example. Their controller might be different too. They're external, short-use drives, so I don't care.

    So, returning to previously mentioned ones, from their respective datasheets:

        - 870 EVO: Samsung V-NAND 3bit MLC
    - 980 Pro: Samsung V-NAND 3bit MLC
    - 990 Pro: Samsung V-NAND TLC
    - KC3000: NAND: 3D TLC
    - NV2: NAND: 3D // Explicit Lottery.

      A bit confused … the article is about Ssd drive with 500- M. Is what it said and discussed more details here applied to nvme drive with 1000+ M. Same?

I bought up a lot of 960 and 970 Pro models when the 980 came out and it was TLC, to have MLC drives for logs and caches. Little did I know that TLC was just the beginning of the decline and QLC was right around the corner for even enterprise!
