M.2 2242 SATA SSD for thin laptops

The Dogfish Technology 2242-120GB is a 120GB internal solid-state drive built in the M.2 2242 form factor with a SATA III 6 Gb/s interface. It uses 3D NAND flash and an SMI controller to deliver sequential reads up to 500 MB/s and writes up to 300 MB/s. The module measures 42 mm by 22 mm and weighs 7.0 g.

Fits 22 mm wide slots in ultraportables

This drive suits owners of thin-and-light laptops or small desktops that accept a 2242-length SATA module and need a modest capacity boost. Systems requiring a longer M.2 card, a PCIe interface or higher throughput should consider other options.

SATA III 6 Gb/s interface decides compatibility

The drive communicates over the SATA III 6 Gb/s protocol through the M.2 2242 connector, so the host must provide a SATA-wired M.2 slot. A PCIe-only slot will not work with this module.

Questions about this item

What sustained write speed can I expect before the drive slows down?

The drive is rated for up to 300 MB/s sequential write; sustained workloads will stay within the SATA 6 Gb/s link limit.

How much heat and noise does the drive add during all-day operation?

With no moving parts and a 7 g weight, it adds negligible heat and runs silently; the operating range is 0 °C to 75 °C.

Which slot and protocol must my laptop already have for this drive to work?

An M.2 2242 key slot wired for SATA is required; the drive is 42 mm long, 22 mm wide and 3.2 mm thick.
