Corsair MP600 Mini 2TB: Handheld-Ready PCIe 4.0 (2026)
The Corsair MP600 Mini 2TB is a compact M.2 2230 PCIe 4.0 SSD rated for 7,000 MB/s reads, purpose-built for Steam Deck and handheld PC upgrades.
Controller & Memory
The MP600 Mini 2TB runs a 4-channel Phison PS5027-E27T controller with Kioxia 162-layer 3D TLC NAND and no onboard DRAM, relying on Host Memory Buffer for its mapping tables instead. This 2024 refresh (identified by the E27T controller) replaced the original MP600 Mini's older Phison E21T platform, roughly doubling rated sequential speed while keeping the same compact M.2 2230 form factor that fits the Steam Deck, ASUS ROG Ally, and Microsoft Surface devices.
Corsair sells this MP600 Mini generation in 1TB and 2TB capacities. Both match on sequential speed and random write IOPS, but the 2TB rates lower on random read IOPS at 750,000 versus the 1TB's 1,000,000, an unusual pattern where the smaller capacity isn't simply outclassed across the board. The 2TB does carry double the endurance rating at 1,200 TBW.
At just 30mm long, the MP600 Mini 2TB is one of the few PCIe 4.0 drives that physically fits inside handheld gaming PCs and 2230-slot ultrabooks, competing against other M.2 2230 upgrades like the WD Black SN770M and the older-generation Corsair MP600 Core Mini, which uses QLC NAND instead of this drive's TLC. A thermal pad is included in the box specifically for Microsoft Surface installations, where thermal contact with the device chassis matters more than in a Steam Deck's open internal layout.

MP600 Mini 2024 Edition Performance & Benchmarks
The 2TB MP600 Mini is rated for 7,000 MB/s sequential reads and 6,200 MB/s sequential writes, with random performance rated at 750,000 IOPS reading and 1,000,000 IOPS writing, notably fast for a drive this physically small. Reviewers testing this E27T-based refresh found it among the fastest M.2 2230 drives available, a meaningful jump over the original MP600 Mini's roughly 4,800 MB/s rating.

- Patriot Viper PV593 4 TB: 14,500 MB/s read, 14,000 MB/s write
- Patriot Viper PV573 2 TB: 14,000 MB/s read, 12,000 MB/s write
- Corsair MP600 Mini 2024 Edition 2 TB (this drive): 7,000 MB/s read, 6,200 MB/s write
Like other DRAM-less TLC drives, the MP600 Mini leans on an SLC write cache and Host Memory Buffer to hit its rated numbers; independent testing of this line found the cache sized around 50GB, after which sustained writes settle to roughly 1,440 MB/s. For Steam Deck and handheld use, this is more than enough for fast game loads and library transfers, and 2TB is large enough to hold a substantial portion of a modern game library without needing to manage storage as tightly as the 1TB capacity requires. PCIe 4.0 bandwidth is also more headroom than most handhelds' own PCIe lanes can fully exploit today, so the drive is unlikely to be the bottleneck as future handheld chipsets improve.

Endurance, TBW & Warranty
The 2TB MP600 Mini carries a 1,200 TBW endurance rating, double the 1TB's rating, and a 5-year warranty. At a realistic handheld or light-desktop workload of 20 to 30GB written per day, 1,200 TBW takes roughly 110 to 164 years to exhaust, far beyond the warranty window and the drive's realistic service life. Corsair does not publish an MTBF figure for this capacity, so treat any third-party reliability estimate as unconfirmed. The 5-year warranty matches full-size M.2 2280 flagships despite this drive's much smaller footprint, and it applies equally whether the drive is installed in a Steam Deck, a laptop, or a desktop adapter card.

Verdict: Is the MP600 Mini 2024 Edition Worth It in 2026?
The MP600 Mini 2TB suits Steam Deck, ROG Ally, and Surface owners who want a fast M.2 2230 upgrade with room for a larger game library than the 1TB provides. Buyers with a standard M.2 2280 slot who don't need the compact form factor get more capacity-per-dollar choices from full-size drives instead. The WD Black SN770M is the closest direct M.2 2230 rival, while Corsair's own MP600 Core Mini offers a cheaper QLC-based alternative with lower rated performance. For a handheld storage upgrade with room to spare, the MP600 Mini 2TB's 7,000 MB/s reads, 1,200 TBW endurance, and full 5-year warranty make it a strong pick.
