WD_BLACK SN8100 2TB ($459) vs Sabrent Rocket 5 2TB ($389). $/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 the SMI SM2508 — a 6nm Gen 5 controller running notably cooler than first-gen Phison E26 designs. The Sabrent Rocket 5 2TB pairs an original Phison E26 chip that defined the Gen 5 reference design.
The cheaper drive — Sabrent Rocket 5 2TB at $194.50/TB — saves you $35.00 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 Sabrent Rocket 5 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 Sabrent Rocket 5 2TB's 11,600 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 Sabrent Rocket 5 2TB is the right call if the lower retail price ($389 vs $459), and better $/TB economics ($194.50/TB) matter to you. Sabrent's Rocket line carries a community reputation for transparent firmware support — manual update tools available directly from the manufacturer.
