The Team Group MP44S is a 2TB M.2 2230 PCIe 4.0 NVMe SSD suited to Steam Deck owners seeking a compact internal storage upgrade, with sequential speeds up to 5,000 MB/s read and 3,500 MB/s write.
Recommended For
- Steam Deck owners replacing a smaller internal drive who want room for a large installed game library; reviewers found its performance adequate for the Deck’s PCIe 3.0 slot.
- ROG Ally or Ally X owners seeking a 2TB internal storage upgrade in the compact M.2 2230 format; reviews describe it as a suitable handheld drive, with QLC performance trade-offs worth considering for the Ally.
- Owners of other compatible devices with an M.2 2230 slot, such as the ROG Flow Z13, who need compact internal storage for games, videos, or other large files.
- Handheld gamers who prefer a larger internal game library over carrying or relying on separate portable storage; reviewers note the appeal of internal SSD storage for mobile use.
Real-World Use Scenarios
- A Steam Deck owner replaces a smaller internal drive to keep more large games installed at once; after setup, the 2TB model provides about 1.84TB of usable space with SteamOS installed.
- A Steam Deck user who prefers internal storage for an emulation collection can keep more games on the device instead of managing a smaller drive; one community owner reports using the 2TB MP44S for emulation.
- A Steam Deck owner upgrading the internal drive should plan to open the handheld and reinstall or transfer SteamOS; once installed, the added capacity is the main practical benefit, rather than a major speed boost over the Deck’s PCIe 3.0 storage connection.
- A gaming-handheld owner with a compatible M.2 2230 slot, such as an original ROG Ally, can use the MP44S to expand internal game storage; confirm the exact device’s drive size and interface before buying.
- Someone using a compatible compact device for games and personal files can consolidate more data on one small internal drive; the MP44S is a 2230-format option, but the device must support that form factor.

Reference Q&A
Q: Teamgroup MP44S 2TB or WD Black SN770M 2TB for a handheld?
A: Choose the MP44S when 2TB capacity at a lower purchase price is the priority. Choose the SN770M if you expect frequent, long write workloads or value higher endurance: the MP44S uses QLC NAND and is rated for 450TBW, while the SN770M uses TLC NAND and is rated for 1,200TBW. For ordinary game storage in a Steam Deck, the MP44S’s capacity and PCIe 3.0-compatible performance make it a practical fit; the SN770M’s advantages matter more for sustained writes and higher-endurance use.
Q: Is the MP44S 2TB a worthwhile upgrade from a 512GB Steam Deck SSD?
A: It is a capacity-focused upgrade: 2TB provides four times the nominal storage of a 512GB drive, giving more room for installed games. The MP44S is an M.2 2230 NVMe drive, and TEAMGROUP says it is compatible with PCIe Gen3 sockets. A Steam Deck will not use the drive’s full PCIe Gen4-rated sequential speeds, so choose it primarily for the extra storage rather than expecting Gen4 peak transfer rates.
Q: Should I get the MP44S 1TB or 2TB?
A: Choose the 2TB model if you keep many large games installed and want to reduce how often you uninstall or rotate them. Choose 1TB if you typically keep a smaller active library and want less capacity. TEAMGROUP lists the same maximum sequential read and write speeds for both capacities; the rated endurance is 450TBW for 2TB and 250TBW for 1TB.
Q: Will this SSD work as a Steam Deck storage upgrade?
A: The MP44S is a 2TB M.2 2230 NVMe SSD listed as Steam Deck compatible. Check that your device uses an M.2 2230 NVMe drive before buying; installing an internal SSD requires opening the device.
Q: Is 2TB a good choice if I’m running out of storage?
A: It’s suitable if you want substantially more internal space for games and other files. The drive provides 2TB of capacity; whether that is worthwhile depends on how much storage you currently need and whether you’re comfortable replacing the device’s internal SSD.
Q: Will this PCIe 4.0 SSD work in a PCIe 3.0 device?
A: Yes. The MP44S is specified as compatible with PCIe Gen3. In a Gen3 system, it can operate at the speeds supported by that system rather than its listed maximum Gen4 sequential speeds of up to 5,000 MB/s read and 3,500 MB/s write.
Q: Is the MP44S 2TB a suitable internal storage upgrade for a Steam Deck?
A: It is an M.2 2230 NVMe drive, and the product listing identifies it as Steam Deck compatible. Reddit users also report using this 2TB model in a Steam Deck. Check your device’s requirements before installation; replacing an internal SSD requires opening the device.
Q: Is it worth paying extra for a faster 2230 SSD for a Steam Deck?
A: Probably not for the advertised peak speed alone: the MP44S is rated up to 5,000 MB/s read and 3,500 MB/s write, while Reddit discussion notes that Steam Deck interface and download speeds can limit how much of a faster drive’s peak performance is useful. A faster model may make more sense if you also plan to use it in a device that can better use its speed.
Q: Does the MP44S use TLC or QLC NAND, and does that matter?
A: The provided product specifications do not identify the NAND type, so they do not establish whether this specific model uses TLC or QLC. Reddit users have raised the same uncertainty. If NAND type or sustained-write behavior is important to your decision, verify the specifications for the exact model revision before buying.
