Side-by-side: Crucial T710 2TB ($435) vs Crucial T705 4TB ($613). $/TB winner, specs, real-world picks for July 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 an SMI SM2508 controller that drew industry attention in 2024 for finally taming Gen 5 thermals. The Crucial T705 4TB pairs Phison's E26 silicon, which kicked off the consumer Gen 5 era and typically requires a heatsink.
Money matters here — $153.25/TB on the Crucial T705 4TB versus $217.50/TB on the Crucial T710 2TB. That's enough of a spread that for budget-conscious builders, the Crucial T705 4TB becomes the default unless reviews of your specific workload prefer the Crucial T710 2TB.
Crucial T705 4TB earns higher TBW ratings (2,400 vs 1,200 TBW) — relevant for sustained write workloads, irrelevant for everything else.
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. For content creators routinely rendering 4K or 8K video, the Crucial T710 2TB's 14,000 MB/s sustained write is the deciding factor — multi-GB project files land noticeably faster than on the alternative. Note for handheld gamers: M.2 2280 is the desktop/laptop standard. Steam Deck and the ROG Ally line need 2230 drives — neither Crucial T710 2TB nor Crucial T705 4TB fits without modification.
Market context: the Crucial T710 2TB ranks #10 of 11 Gen 5 2 TB drives we track by $/TB, while the Crucial T705 4TB ranks #2 of 6 Gen 5 4 TB drives. One of them is genuinely among the cheapest options in its class, so this matchup includes a real value pick.
Go with the Crucial T710 2TB for the lower retail price ($435 vs $613), and higher sustained writes (14,000 MB/s). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
Go with the Crucial T705 4TB for better $/TB economics ($153.25/TB), and a higher TBW endurance rating (2,400 TBW). Crucial's T-series tends to undercut Samsung and WD on price while using comparable Micron silicon — a value play hiding in a flagship form factor.
