Compare Crucial T705 2TB and Corsair MP700 PRO XT 2TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both the Crucial T705 2TB and Corsair MP700 PRO XT 2TB sit in the Gen 5 category at 2 TB, so the matchup turns on controller efficiency, cache topology, and current pricing rather than raw class differences.
Hardware-wise, the Crucial T705 2TB runs on an original Phison E26 chip that defined the Gen 5 reference design. The Corsair MP700 PRO XT 2TB pairs Phison's E28 design, manufactured on a more efficient process than the E26.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Crucial T705 2TB and Corsair MP700 PRO XT 2TB to roughly equal in-game load times. The cheaper drive is the smart pick. Note for handheld gamers: M.2 2280 is the desktop/laptop standard. Steam Deck and the ROG Ally line need 2230 drives — neither Crucial T705 2TB nor Corsair MP700 PRO XT 2TB fits without modification.
Pick the Crucial T705 2TB if you value the lower retail price ($399 vs $419), and better $/TB economics ($199.50/TB). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
Corsair pairs the E28 controller with quality Kioxia BiCS8 NAND in the MP700 PRO XT — same flash class as the WD SN8100 at a different price point.
