Sabrent Rocket 5 1TB ($259) vs WD_BLACK SN850X 1TB ($220). $/TB analysis, performance, and use-case recommendations.
When generations cross paths in a comparison like this one, the older-spec drive almost always wins on value while the newer one wins on benchmarks. Whether that benchmark advantage matters depends entirely on what you do with the drive.
Hardware-wise, the Sabrent Rocket 5 1TB runs on an original Phison E26 chip that defined the Gen 5 reference design. The WD_BLACK SN850X 1TB pairs WD's G2 controller — manufactured by SanDisk and tuned for low-latency gaming workloads.
The cheaper drive — WD_BLACK SN850X 1TB at $220.00/TB — saves you $39.00 per TB versus the Sabrent Rocket 5 1TB. Worth it if you're capacity-constrained; either works if you just want one fast drive.
In the read department, the Sabrent Rocket 5 1TB leads by roughly 6 GB/s. The difference is more academic than practical for typical use, but it does matter for video editors moving multi-GB project files.
Write performance separates them too. The Sabrent Rocket 5 1TB sustains 11,600 MB/s writes versus 6,300 MB/s for the WD_BLACK SN850X 1TB — a real advantage for video editors and anyone doing heavy file operations.
For PlayStation 5 builds, the console's internal M.2 slot tops out around 5,500 MB/s sustained, so both Sabrent Rocket 5 1TB and WD_BLACK SN850X 1TB hit the same wall — pick whichever is cheaper at the moment you buy. The Gen 5 Sabrent Rocket 5 1TB pulls ahead on sequential bandwidth, but Gen 5 advantages rarely surface during everyday tasks — most software hasn't been rewritten to exploit 14,000+ MB/s pipelines. For content creators routinely rendering 4K or 8K video, the Sabrent Rocket 5 1TB's 11,600 MB/s sustained write is the deciding factor — multi-GB project files land noticeably faster than on the alternative. Note for handheld gamers: M.2 2280 is the desktop/laptop standard. Steam Deck and the ROG Ally line need 2230 drives — neither Sabrent Rocket 5 1TB nor WD_BLACK SN850X 1TB fits without modification.
Market context: the Sabrent Rocket 5 1TB ranks #5 of 6 Gen 5 1 TB drives we track by $/TB, while the WD_BLACK SN850X 1TB ranks #2 of 4 Gen 4 1 TB drives. Neither cracks the top of the value table, so it's worth glancing at the alternatives below before picking either.
As of July 27, 2026, these tracked drives undercut both the Sabrent Rocket 5 1TB and WD_BLACK SN850X 1TB on $/TB:
The Sabrent Rocket 5 1TB is the right call if meaningfully faster reads (14,000 MB/s), and higher sustained writes (11,600 MB/s) matter to you. Sabrent's Rocket line carries a community reputation for transparent firmware support — manual update tools available directly from the manufacturer.
The WD_BLACK SN850X 1TB is the right call if the lower retail price ($220 vs $259), and better $/TB economics ($220.00/TB) matter to you. Among Gen 4 flagships, the SN850X strikes a sweet spot — premium silicon at sub-Samsung pricing, with WD's established RMA process to back it up.
