2242 Form Factor 2TB SATA SSD

The Dogfish Technology 2242-2TB is a M.2 2242 internal solid state drive with a 2TB capacity. It connects through a SATA III 6 Gb/s interface and uses 3D NAND QLC flash memory. The drive is designed for consumer desktop and laptop upgrades.

Suits SATA M.2 slots only

This drive fits systems with an M.2 2242 slot wired for SATA signalling. It will not work in slots limited to PCIe signalling. Buyers with shorter M.2 lengths or PCIe-only platforms should select a different form factor or interface.

Sequential read up to 550 MB/s

The drive delivers sequential reads up to 550 MB/s and writes up to 400 MB/s. It supports DevSleep low power state, TRIM, NCQ and S.M.A.R.T. monitoring. These speeds are typical for SATA III SSDs in this form factor.

Questions about this item

Will the 3D NAND QLC cells on this 2TB drive wear out faster than other types?

The drive uses 3D NAND QLC flash with built-in ECC, bad-block management and wear-levelling algorithms to extend cell life under normal consumer workloads.

What limits sustained write performance on this SATA III 6 Gb/s model?

Sequential write tops out at 400 MB/s, so the SATA interface and controller firmware become the bottleneck before the NAND saturates during long transfers.

How much heat and noise does the M.2 2242 module produce in all-day operation?

With no moving parts and DevSleep ultra-low-power support, the drive runs silently and adds minimal heat to a laptop or desktop chassis.
