256GB SATA M.2 2242 SSD

This 256GB internal solid-state drive uses the M.2 2242 form factor and a SATA III interface. It is built with 3D NAND flash memory and an SMI controller for consumer workloads. The drive measures 22mm wide by 42mm long and weighs 7g.

SATA M.2 slot required; not for PCIe-only sockets

The drive fits laptops and desktops that provide a SATA-based M.2 2242 socket. Systems with PCIe-only M.2 slots cannot use this SATA device. Buyers should verify their motherboard or laptop manual for SATA M.2 support before purchase.

Sequential read up to 550 MBps

Maximum sequential read reaches 550 MBps and sequential write reaches 400 MBps over the SATA III link. These speeds suit OS boot, application loading and general file storage. Performance will not exceed the SATA III interface limit.

商品問答

Does the Dogfish 2242-256GB come with a mounting screw or adapter, or do I need to buy them separately?

The drive itself is the only component supplied; a mounting screw or M.2 adapter is not included and must be sourced separately if your system requires one.

Why choose the 256 GB SATA III model instead of a larger capacity or a PCIe version?

This 256 GB SATA III unit fits the M.2 2242 slot and delivers up to 550 MB/s read and 400 MB/s write, matching older laptops and small-form-factor PCs that lack PCIe support.

What does the 550 MB/s sequential read figure mean once the drive is installed in my laptop?

In a SATA III system the drive can sustain up to 550 MB/s reads and 400 MB/s writes, so boot times and file transfers will be limited by the SATA interface rather than the NAND.
