WD_BLACK SN8100 2TB ($380) vs Sabrent Rocket 5 2TB ($350). $/TB analysis, performance, and use-case recommendations.
WD_BLACK SN8100 2TB and Sabrent Rocket 5 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 Sabrent Rocket 5 2TB pairs the Phison E26 — the first widely-deployed Gen 5 controller, capable but thermally demanding.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (14,000 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the Sabrent Rocket 5 2TB. Video editors will gravitate toward the Sabrent Rocket 5 2TB for its write headroom (11,600 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.
