M.2 2242 SATA SSD for compact systems

This internal solid-state drive uses the M.2 2242 form factor and a SATA III interface to deliver 1TB of storage. It fits laptops and small-form-factor desktops that accept a 22mm by 42mm module. The drive uses 3D NAND flash memory and a SMI controller for consumer workloads.

SATA III interface limits peak throughput

The SATA III 6 Gb/s connection caps sequential reads at 550 MBps and writes at 500 MBps. This ceiling is set by the interface itself, not the drive firmware. Systems limited to SATA will not exceed these speeds regardless of the SSD installed.

1TB capacity decides fit for purpose

The single specification that determines suitability is the 1TB capacity. It must match the space required for the operating system, applications and working files in the target device.

Questions about this item

Which capacity and form factor should I pick for a 1 TB upgrade in an M.2 2242 slot?

Choose the 1 TB M.2 2242 model; it fits the 22 mm by 42 mm slot and delivers the full 1 TB capacity.

What do the 550 MBps read and 500 MBps write speeds mean once the drive is installed in my laptop?

Those are the maximum sequential transfer rates over the SATA III link; real-world speeds will be slightly lower but still near the SATA 6 Gb/s ceiling.

How does the SATA III interface limit performance compared with faster standards?

SATA III caps sequential throughput at roughly 550 MBps, so this drive saturates the bus and cannot reach the 2200 MBps seen on PCIe models.
