Samsung 850 EVO 250GB 2.5" SATA SSD

This internal solid state drive uses Samsung V-NAND technology and a MGX controller to deliver sequential reads up to 540 MBps and writes up to 520 MBps. The 250GB capacity suits everyday computing in laptops and desktops that accept a 2.5 inch SATA drive. It operates from 0°C to 70°C with active power draw of 3.5W.

SATA III interface

The drive connects through a SATA III interface compatible with SATA 3Gb/s and SATA 1.5Gb/s ports. This single specification decides whether the SSD fits your system; it will not work in M.2 or PCIe slots. Maximum random read reaches 97,000 IOPS at QD32 while random write reaches 88,000 IOPS at QD32.

Samsung Data Migration and Magician software

Free downloadable utilities simplify cloning an existing drive and provide ongoing health monitoring, firmware updates and performance optimisation. The software bundle turns a bare drive into a managed upgrade path for Windows 7 and above. No mounting hardware or cables are included in the package.

Questions about this item

What does the 540 MB/s sequential read speed mean for everyday use?

The drive can deliver up to 540 MB/s sequential reads over SATA III, so large file loads and boot sequences run at the interface limit.

How does the SATA III interface cap performance in practice?

SATA III tops out at 6 Gb/s, so the 540 MB/s read and 520 MB/s write figures sit at the bus ceiling.

Will the 6.86 mm height fit my laptop drive bay?

At 6.86 mm tall the drive matches the standard 2.5" form factor used in most laptops and desktops.
