Dogfish 2242 SATA 500GB

The Dogfish Technology 2242-500GB Three Colour is an M.2 2242 internal SSD with a 500GB capacity and a SATA 6 Gb/s interface. It uses 3D NAND components and measures 22mm wide by 42mm long by 3.2mm thick. The drive weighs 20g and is rated for 1,000,000 hours MTBF.

Suits SATA M.2 slots only

This drive fits devices that accept a 42mm M.2 module with a SATA interface. It will not work in slots wired exclusively for PCIe signalling. Buyers with PCIe-only M.2 slots or 2.5-inch bays should choose a different form factor.

Sequential speeds up to 500MBps

The specification lists maximum sequential read and write speeds of up to 500MBps, with ATTO benchmarks showing 500MBps read and 450MBps write. If your workload demands higher throughput, a PCIe-based SSD would be required.

Questions about this item

My laptop has a 42 mm M.2 slot that supports SATA; will this 2242 500 GB drive fit and work?

The drive uses the M.2 2242 form factor measuring 22 mm wide by 42 mm long and connects through a SATA III 6 Gb/s interface so it will install and operate in any compatible slot.

I plan to keep my older 2.5 inch SATA SSD as a secondary drive; can both run together?

Yes, this M.2 SATA SSD and a 2.5 inch SATA drive use the same protocol and can coexist as long as the motherboard provides separate SATA ports or an M.2 slot wired for SATA.

After fitting the drive how can I confirm it is delivering the rated 500 MB/s read speed?

Run a sequential read test such as ATTO or CrystalDiskMark; a healthy result will show speeds approaching the specified 500 MB/s maximum.
