Side-by-side: Crucial T710 2TB ($449) vs Crucial T705 4TB ($749). $/TB winner, specs, real-world picks for May 2026.
Both run on Gen 5 hardware but at different capacities: 2 TB for the Crucial T710 2TB versus 4 TB for the Crucial T705 4TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
Hardware-wise, the Crucial T710 2TB runs on the SMI SM2508 — a 6nm Gen 5 controller running notably cooler than first-gen Phison E26 designs. The Crucial T705 4TB pairs an original Phison E26 chip that defined the Gen 5 reference design.
Prices favor the Crucial T705 4TB by $37.25/TB ($187.25/TB versus $224.50/TB). Not a huge gap, but enough to be the tiebreaker if performance is similar.
On warranty endurance the Crucial T705 4TB carries 2,400 TBW against Crucial T710 2TB's 1,200 TBW. Both will outlast typical use, but the gap matters if you're doing professional content work.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Crucial T710 2TB and Crucial T705 4TB to roughly equal in-game load times. The cheaper drive is the smart pick. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Crucial T710 2TB's 14,000 MB/s sustained write speed. Both drives use the 2280 form factor, which is too long for Steam Deck or ROG Ally — you'd need a 2230 variant if either manufacturer offers one, or a dedicated handheld-format drive instead.
Go with the Crucial T710 2TB for the lower retail price ($449 vs $749), and higher sustained writes (14,000 MB/s). Crucial drives benefit from being a direct Micron product — the same NAND that powers competitors' drives, but at lower margins.
Go with the Crucial T705 4TB for better $/TB economics ($187.25/TB), and a higher TBW endurance rating (2,400 TBW). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
