240GB M.2 SATA SSD

The Kingston A400 SA400M8/240G is a 240GB internal solid-state drive built in the M.2 2280 form factor with a SATA III interface. It uses 3D NAND components and a latest-generation controller to deliver sequential read speeds up to 500 MBps and write speeds up to 350 MBps. The drive draws 0.195 W idle and 0.279 W average active power.

Desktop and notebook upgrade

This drive suits users replacing a mechanical hard drive in a desktop or notebook that has an M.2 slot wired for SATA. It brings faster boot, application loading and file transfers without moving parts, improving reliability and durability. Systems with M.2 slots limited to PCIe only cannot use this SATA drive.

SATA III interface

The single specification that decides compatibility is the SATA III interface combined with the M.2 2280 physical layout. The motherboard must provide a SATA lane to the M.2 connector; a PCIe-only slot will not work with this SSD.

Questions about this item

How do I confirm the SA400M8/240G is performing at up to 500 MBps read and 350 MBps write after installation?

Run a SATA benchmark tool such as CrystalDiskMark; sequential results should approach 500 MBps read and 350 MBps write on a SATA III port.

What comes with the SA400M8/240G and what must I source separately?

The box contains the 240GB M.2 2280 drive only; you need a motherboard with an M.2 SATA slot and a mounting screw.

Which A400 capacity should I choose between 120GB, 240GB and 960GB?

120GB suits a light OS drive, 240GB adds space for core applications, and 960GB covers large libraries or full drive replacement.
