The Samsung 870 EVO is a 2.5-inch SATA III solid-state drive built on Samsung's V-NAND and controller, rated at 560 MB/s sequential read and 530 MB/s sequential write. It is the top capacity in Samsung's mainstream SATA line, with an endurance rating of up to 2,400 TBW and a five-year limited warranty. It suits desktop and laptop upgrades, NAS boxes and video recorders that take a 2.5-inch SATA drive. Against SATA rivals like the Crucial MX500 and WD Blue, it matches their interface ceiling and adds Samsung's track record and the Magician software; it is not faster than those drives, and it is far slower than any NVMe drive on a modern board.

Owners of the 870 EVO line generally report it works as advertised: fast for SATA, reliable over years of use, and easy to install with Samsung's migration and Magician tools. The main complaints are about price relative to other SATA drives and about the SATA speed ceiling itself.
The Samsung 870 EVO is a 4TB 2.5-inch SATA III internal SSD for PCs. It reaches the SATA interface limit, with sequential speeds of up to 560 MB/s read and 530 MB/s write. A larger variable buffer speeds up writes and helps maintain high performance over time.
It is rated for up to 2,400 TBW, for tasks from everyday computing to 8K video processing. It supports AES 256 encryption (Class 0), TCG/Opal v2.0 and MS eDrive (IEEE1667).
The drive has been compatibility tested with major host systems and applications, including chipsets, motherboards, NAS and video recording devices.
