Compact M.2 2242 SATA drive

The Dogfish Technology 2242-500GB is an internal solid-state drive built for laptops and desktops that accept a 42 mm M.2 module. It uses 3D NAND flash and a SATA III interface to deliver 500 GB of storage in a 22 mm by 42 mm footprint.

Upgrade from mechanical storage

Replacing a 2.5-inch hard drive with this drive removes moving parts, cuts noise and reduces heat output. The jump is worth it when a system needs faster boot times and quicker application loading without changing the motherboard interface.

Steady throughput under load

Sequential reads reach 570 MB/s and writes reach 500 MB/s in sustained transfers. The controller maintains these rates across long write sessions while operating between 0 °C and 75 °C, backed by a 1,000,000-hour MTBF rating.

Questions about this item

Will this M.2 2242 drive fit my laptop's slot?

The drive uses the M.2 2242 form factor, measuring 22 mm wide by 42 mm long. Verify your device has an M.2 slot that accepts 42 mm length cards before purchasing.

What sequential speeds can I expect from this SATA SSD?

The manufacturer rates sequential read up to 570 MBps and sequential write up to 500 MBps using ATTO benchmark. Real-world speeds depend on your system's SATA controller and workload.

Does the 3D NAND TLC design affect endurance or reliability?

3D NAND TLC with the SMI controller helps reduce cell-to-cell interference. The drive carries a 1,000,000-hour MTBF rating and operates from 0 °C to 75 °C for typical consumer workloads.
