WD_BLACK SN8100 2TB ($459) vs Corsair MP700 PRO XT 2TB ($419). $/TB analysis, performance, and use-case recommendations.
WD_BLACK SN8100 2TB and Corsair MP700 PRO XT 2TB are direct competitors — same generation, same capacity. Choose by controller behavior under sustained load, DRAM/HMB cache strategy, and $/TB economics.
Hardware-wise, the WD_BLACK SN8100 2TB runs on the SMI SM2508 — a 6nm Gen 5 controller running notably cooler than first-gen Phison E26 designs. The Corsair MP700 PRO XT 2TB pairs an updated Phison E28 that addressed the thermal complaints of its predecessor.
The cheaper drive — Corsair MP700 PRO XT 2TB at $209.50/TB — saves you $20.00 per TB versus the WD_BLACK SN8100 2TB. Worth it if you're capacity-constrained; either works if you just want one fast drive.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both WD_BLACK SN8100 2TB and Corsair MP700 PRO XT 2TB 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 Corsair MP700 PRO XT 2TB's 12,700 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 WD_BLACK SN8100 2TB fits buyers who prefer its specific performance profile or have brand preference for WD.
The Corsair MP700 PRO XT 2TB is the right call if the lower retail price ($419 vs $459), better $/TB economics ($209.50/TB), and higher sustained writes (12,700 MB/s) matter to you. The MP700 PRO XT positioned itself as the cooler-running Gen 5 alternative when Samsung's 9100 PRO and WD's SN8100 were heatsink-dependent.
