Manufacturer description

The WD Green 240GB M.2 2280 SATA SSD is Western Digital's entry-level solid-state upgrade for desktop builds that still run on a SATA 6Gb/s bus. It reads sequentially at up to 545 MB/s, which is the practical ceiling of the SATA interface and roughly five to six times what a spinning 7200 RPM drive delivers on boot and application loads. If your motherboard has a spare M.2 slot wired for SATA rather than PCIe, this is the drive that fits it without adapters or extra cabling. Western Digital rates idle draw down to 30mW, so it suits small-form-factor and low-power desktop builds where thermal…

Frequently Asked Questions

Is this an NVMe drive or a SATA drive?

It is a SATA drive in an M.2 2280 form factor, running on the SATA 6Gb/s interface at up to 545 MB/s sequential read. Your motherboard's M.2 slot must support SATA mode, not PCIe-only.

How fast is the WD Green 240GB compared to a hard drive?

Sequential reads reach up to 545 MB/s versus roughly 100-150 MB/s from a typical desktop hard drive, so boot and application load times drop substantially.

Will this fit my laptop?

Western Digital lists desktop as the compatible device type for this model. Confirm your laptop's M.2 slot length (2280) and that it accepts SATA-mode M.2 drives before ordering.

Can I move my existing Windows install to it?

Yes. Western Digital provides downloadable cloning and backup software alongside the WD SSD Dashboard utility, so you can clone your current drive instead of reinstalling.

Is 240GB enough storage?

It is sized for a boot drive holding Windows and core applications. With modern games running 80-150GB each, plan on a secondary drive for a game library.
