SAMSUNG 870 QVO SATA III SSD 2TB 2.5" Internal Solid State Drive

Manufacturer description

The Samsung 870 QVO 2TB brings 2.5-inch SATA simplicity to a desktop or laptop that has run out of room. As Samsung's 2nd-generation QLC drive, it pushes sequential reads and writes up to 560/530 MB/s — the practical ceiling of the SATA interface — and Samsung rates its read performance up to 13 percent faster than the outgoing 860 QVO.

Is QLC NAND reliable enough for daily use?

Samsung states the 870 QVO provides endurance equivalent to 3-bit MLC SSDs for daily use, with the family rated up to 1,440 TBW and the 8TB model reaching 2,880 TBW via a refined ECC algorithm.

Do I need extra software to migrate my existing drive?
