Dogfish M.2 2242 SATA III SSD

The Dogfish 2242-128GB is an internal solid-state drive built in the M.2 2242 form factor. It connects through a SATA III interface and provides 128 GB of storage using 3D NAND flash memory. Sequential reads reach up to 550 MB/s and writes up to 400 MB/s. The drive weighs 20 g and measures 42 mm by 22 mm by 3.2 mm.

Who this suits and who should look elsewhere

This drive fits laptops and desktops that have an M.2 slot wired for SATA signalling. It is designed for consumer workloads such as operating system boot, application loading and general file storage. Systems that require a PCIe interface or a different M.2 length cannot use this module. Buyers needing higher capacities or faster transfer rates should consider other models.

The specification that decides fit

The interface is SATA III running at 6 Gb/s. The motherboard slot must support SATA over the M.2 connector; a slot that only carries PCIe lanes will not recognise the drive. Verify the slot specification before purchase.

Questions about this item

How can I confirm the drive is working correctly after installing it in my laptop?

After installation, verify the drive appears in BIOS or Disk Management at 128GB capacity. Run a health check with a S.M.A.R.T. tool to confirm temperature reads 0°C to 75°C and no reallocated sectors are reported.

What comes in the package and do I need any extra parts to fit it?

The box contains the 22mm by 42mm M.2 2242 SSD weighing 20g. No cables or brackets are included; most laptops secure the drive with a single M2 screw that is already on the motherboard.

Which capacity should I choose if I want the fastest sequential speeds in this series?

This model is the 128GB variant with up to 550 MBps read and 400 MBps write. Higher capacities in the same SATA III series share these speed ratings, so capacity choice depends on storage needs rather than performance.
