Manufacturer Contact Info

The Team Group MP44S is a 1TB M.2 2230 PCIe 4.0 x4 NVMe SSD designed for Steam Deck capacity upgrades and other compatible compact devices, with sequential read speeds up to 5,000 MB/s and write speeds up to 3,500 MB/s.

Recommended For

Steam Deck owners replacing a smaller internal drive who want more room for installed games; testing found the 1TB MP44S performed comparably to other drives in the Deck, where capacity mattered more than peak SSD speed.
Owners of compact PCs or handhelds with a compatible M.2 2230 NVMe slot who need a small-form-factor storage upgrade; TEAMGROUP specifically positions the drive for Steam Deck and other lightweight devices.
Handheld gamers who mainly install and launch games rather than transfer very large files repeatedly; Tom’s Hardware found the 1TB model suitable for Steam Deck use despite weaker sustained-write performance in desktop testing.
People upgrading a PCIe Gen 3 device that supports M.2 2230 NVMe and want a Gen 4 drive that can operate at the older interface’s speeds; TEAMGROUP lists the MP44S as backward-compatible with PCIe Gen 3.
