WD_BLACK SN8100 2TB ($380) 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 SMI's SM2508 silicon, which became the default Gen 5 controller for power-conscious flagships. The Corsair MP700 PRO XT 2TB pairs Phison's E28 — the second-gen Gen 5 controller with refined efficiency over the original E26.
The cheaper drive — WD_BLACK SN8100 2TB at $190.00/TB — saves you $19.50 per TB versus the Corsair MP700 PRO XT 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. Video editors will gravitate toward the Corsair MP700 PRO XT 2TB for its write headroom (12,700 MB/s sustained). Project saves and proxies move faster, which compounds across a workday. Heads-up — these are full-length 2280 drives. Steam Deck and most current handhelds require shorter 2230 modules, so check capacity-specific 2230 variants if that's your target platform.
Market context: we track 11 Gen 5 2 TB drives, and by price per terabyte the WD_BLACK SN8100 2TB currently sits #5 while the Corsair MP700 PRO XT 2TB sits #9. Neither cracks the top of the value table, so it's worth glancing at the alternatives below before picking either.
