Samsung 9100 PRO 2TB ($465) vs Crucial T705 4TB ($749). $/TB analysis, performance, and use-case recommendations.
Both run on Gen 5 hardware but at different capacities: 2 TB for the Samsung 9100 PRO 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 Samsung 9100 PRO 2TB runs on Samsung's in-house Presto controller, designed specifically for the 9100 PRO series. The Crucial T705 4TB pairs an original Phison E26 chip that defined the Gen 5 reference design.
The cheaper drive — Crucial T705 4TB at $187.25/TB — saves you $45.25 per TB versus the Samsung 9100 PRO 2TB. Worth it if you're capacity-constrained; either works if you just want one fast drive.
On warranty endurance the Crucial T705 4TB carries 2,400 TBW against Samsung 9100 PRO 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 Crucial T705 4TB wins this matchup on $/TB. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Samsung 9100 PRO 2TB'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.
The Samsung 9100 PRO 2TB is the right call if the lower retail price ($465 vs $749) matter to you. Samsung's PRO line has the longest track record for firmware reliability — over a decade of consumer SSDs with global RMA support.
The Crucial T705 4TB is the right call if better $/TB economics ($187.25/TB), and a higher TBW endurance rating (2,400 TBW) matter to you. Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
