Samsung 870 QVO 2TB SATA SSD

The Samsung 870 QVO 2TB is a 2.5 inch internal solid state drive built for consumer desktops and laptops that use a standard SATA III connection. It uses Samsung 4-bit QLC V-NAND and an MKX controller to deliver up to 560 MBps sequential read and 530 MBps sequential write speeds.

Samsung Magician software included

The bundled Samsung Magician software provides tools to manage the drive, monitor health and status, and keep firmware current. It lets users enable AES 256-bit full disk encryption with TCG/Opal V2.0 and IEEE1667 support without additional licences.

7mm metal case with SATA connectors

The 7.00mm high metal enclosure fits 2.5 inch drive bays in both desktops and laptops. Standard SATA data and power connectors allow direct installation without adapters, while 30 mW idle and 3.0 W active write power keep thermal load low.

Questions about this item

When will the 720 TBW endurance rating of the 2TB 870 QVO require replacement?

The drive is rated for 720 TBW; typical consumer workloads reach that point after several years, at which time the SSD should be replaced.

Does the MKX controller or the SATA III interface limit sustained write speed first?

The SATA III interface caps sequential writes at 530 MB/s, so the interface is the first limit under sustained use.

How much power does the 870 QVO draw and how hot does it get when running all day?

Active read power is 2.2 W and write power is 3.0 W; the drive is rated for 0 °C to 70 °C operating temperature.
