Compare Samsung 9100 PRO 4TB and Crucial T705 2TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both run on Gen 5 hardware but at different capacities: 4 TB for the Samsung 9100 PRO 4TB versus 2 TB for the Crucial T705 2TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
Hardware-wise, the Samsung 9100 PRO 4TB runs on Samsung's in-house Presto controller, designed specifically for the 9100 PRO series. The Crucial T705 2TB pairs an original Phison E26 chip that defined the Gen 5 reference design.
On warranty endurance the Samsung 9100 PRO 4TB carries 2,400 TBW against Crucial T705 2TB's 1,200 TBW. Both will outlast typical use, but the gap matters if you're doing professional content work.
Heading to a PlayStation 5? Both drives drop into the console's M.2 bay and report identical real-world benchmarks since the PS5 caps storage at PCIe 4.0 speeds. The Samsung 9100 PRO 4TB wins this matchup on $/TB. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Samsung 9100 PRO 4TB's 13,400 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.
Pick the Samsung 9100 PRO 4TB if you value better $/TB economics ($192.25/TB), and a higher TBW endurance rating (2,400 TBW). Samsung's PRO line has the longest track record for firmware reliability — over a decade of consumer SSDs with global RMA support.
Pick the Crucial T705 2TB if you value the lower retail price ($399 vs $769). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
