Samsung 850 EVO mSATA 250GB

The Samsung 850 EVO is an internal solid-state drive built in the mSATA form factor with a 250GB capacity. It connects through a SATA III interface and uses the MGX controller. The drive includes data migration software to simplify moving existing files and operating systems onto the new storage.

Upgraders with mSATA slots

This drive suits owners of laptops or compact desktops that have a dedicated mSATA slot and need a capacity boost without changing the motherboard. Systems that only accept 2.5-inch SATA drives or M.2 modules cannot use this mSATA module.

SATA III interface

The SATA III interface determines whether this SSD is compatible with the host system. The drive delivers sequential reads up to 540 MBps and writes up to 520 MBps with random performance of 97,000 IOPS read and 88,000 IOPS write. Active power draw reaches 3.5W for reads and 4.3W for writes.

Questions about this item

Does my laptop need an mSATA slot to install this MZ-M5E250BW?

Yes, the drive uses the mSATA form factor and a SATA III interface, so the host must provide a compatible mSATA connector.

Will this 850 EVO work in a system that only supports SATA II speeds?

The drive is backward compatible with SATA II ports, though sequential reads will be limited to the older bus maximum instead of the rated 540 MBps.

How can I confirm the SSD is delivering its rated 540 MBps read performance after installation?

Run a sequential-read benchmark such as CrystalDiskMark and verify results approach the 540 MBps specification on a SATA III link.
