Side-by-side: Crucial P310 4TB ($519) vs TeamGroup MP44 4TB ($513). $/TB winner, specs, real-world picks for July 2026.
Gen 4 at 4 TB is one of the most contested SSD segments in 2026, and Crucial P310 4TB versus TeamGroup MP44 4TB captures that competition well. The decision rarely comes down to peak speeds — both drives saturate typical workloads.
Hardware-wise, the Crucial P310 4TB runs on Phison's E27T — a four-channel Gen 4 controller for HMB designs. The TeamGroup MP44 4TB pairs a MAP1602 controller built specifically for DRAM-less HMB designs.
TeamGroup MP44 4TB earns higher TBW ratings (3,000 vs 1,760 TBW) — relevant for sustained write workloads, irrelevant for everything else.
PS5 owners get no measurable benefit from either drive's peak speed because Sony's internal NVMe controller throttles to ~5,500 MB/s; treat Crucial P310 4TB and TeamGroup MP44 4TB as interchangeable here and let price decide. Note for handheld gamers: M.2 2280 is the desktop/laptop standard. Steam Deck and the ROG Ally line need 2230 drives — neither Crucial P310 4TB nor TeamGroup MP44 4TB fits without modification.
