The predecessor 860 QVO contributed greatly to the growth of terabyte capacity sales in the SATA SSD market. The 870 QVO provides best in class performance as sequential read (up to 560 MB/s) and write (up to 530MB/s) approaches the limits of performance available with the SATA interface.
I know this 8TB Samsung SSD fairly well (had dozens of it). It's not the fastest, but it's big. It's best used for sequential backups, which is what I've bought this one for -- and it works great.
