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.
