Samsung 860 EVO M.2 2280 250GB SATA III SSD

This Samsung 860 EVO is a 250GB internal solid-state drive in the M.2 2280 form factor. It connects via a SATA III interface and uses 3D NAND memory with an MJX controller and 512MB LPDDR4 cache. The drive suits everyday computing workloads in compatible laptops or desktops.

Suits SATA M.2 slots; not for PCIe-only systems

This drive fits builders upgrading a SATA-based M.2 slot in a laptop or desktop. It delivers sequential reads up to 550 MB/s and writes up to 520 MB/s with random read IOPS up to 97,000 at QD32. Buyers whose motherboards or laptops provide a PCIe-only M.2 slot cannot use this drive and should look for a PCIe model instead.

SATA III interface decides compatibility

The single specification that determines fit is the SATA III interface on an M.2 2280 connector. The drive requires a motherboard or laptop M.2 slot wired for SATA signalling and will not function in slots wired exclusively for PCIe. Verify the slot type before purchase.

Questions about this item

Should I pick the 250GB, 500GB, 1TB or 2TB version?

The 250GB model is the entry capacity; larger versions share the same SATA III interface and 3D NAND technology but provide more space for games and media.

What do the 550 MB/s read and 520 MB/s write figures mean once the drive is installed?

Those are the maximum sequential speeds the controller can sustain over the SATA III link; real-world throughput will be close to those numbers for large file transfers.

What does the SATA III interface cap in practice?

The SATA III connection limits sequential throughput to the quoted 550 MB/s read and 520 MB/s write, and random performance to 97,000 IOPS read and 88,000 IOPS write at QD32.
