Gen 5 at 2 TB is one of the most contested SSD segments in 2026, and Samsung 9100 PRO 2TB versus WD_BLACK SN8100 2TB captures that competition well. The decision rarely comes down to peak speeds — both drives saturate typical workloads.
Hardware-wise, the Samsung 9100 PRO 2TB runs on Samsung's Presto controller — built in-house to push V-NAND to its Gen 5 ceiling. The WD_BLACK SN8100 2TB pairs the SMI SM2508 — a 6nm Gen 5 controller running notably cooler than first-gen Phison E26 designs.
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 WD_BLACK SN8100 2TB wins this matchup on $/TB. Video editors will gravitate toward the Samsung 9100 PRO 2TB for its write headroom (13,400 MB/s sustained).
