250 GB mSATA SSD for compact systems

The Samsung 860 EVO MZ-M6E250BW is a 250 GB internal solid-state drive built for consumer laptops and small-form-factor desktops that accept an mSATA module. It uses the SATA III interface and Samsung V-NAND 3-bit MLC memory to deliver solid-state responsiveness without a 2.5-inch bay.

mSATA form factor and SATA III connection

The mSATA card plugs directly into a compatible slot on the motherboard, removing the need for drive cages or data cables. A Samsung MJX controller manages the flash, while Trim support, S.M.A.R.T. monitoring and an auto garbage-collection algorithm maintain consistent performance over the drive's life. AES 256-bit hardware encryption with TCG Opal and IEEE 1667 compliance protects data at rest.

Low power draw and wide temperature range

Average active consumption is 2.2 W with a 4.5 W burst maximum, and the drive operates from 0 °C to 70 °C. With no moving parts it runs silently and withstands shocks of 1,500 G for 0.5 ms. The controller's device-sleep support further reduces energy use during idle periods, and a 1.5 million-hour MTBF rating reflects the design's durability.

Questions about this item

What practical limit does the SATA III interface put on this mSATA drive?

The SATA III link caps real-world throughput at 550 MBps read and 520 MBps write, so the Samsung MJX controller cannot exceed those figures even though the V-NAND 3-bit MLC flash is faster.

What slot and clearance does the mSATA form factor require?

It needs a standard mSATA connector (full-size, not half-size) and a 70 °C operating-temperature envelope, so the motherboard or adapter must expose a full mSATA socket with adequate airflow.

How is the drive initialised and what step do people skip?

After physical insertion, enable AHCI in the BIOS, partition the 250 GB volume in the OS, then run Samsung Magician to activate TRIM, AES 256-bit encryption and the TurboWrite cache — the Magician step is the one most often missed.
