Sabrent Rocket 5 2TB ($350) vs Crucial P310 2TB ($292). $/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 2TB runs on an original Phison E26 chip that defined the Gen 5 reference design. The Crucial P310 2TB pairs an E27T controller built specifically for DRAM-less Gen 4 SSDs.
The cheaper drive — Crucial P310 2TB at $146.00/TB — saves you $29.00 per TB versus the Sabrent Rocket 5 2TB. Worth it if you're capacity-constrained; either works if you just want one fast drive.
In the read department, the Sabrent Rocket 5 2TB 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 2TB sustains 11,600 MB/s writes versus 6,000 MB/s for the Crucial P310 2TB — a real advantage for video editors and anyone doing heavy file operations.
Cache architecture differs: Sabrent Rocket 5 2TB has DRAM hardware, Crucial P310 2TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
Sabrent Rocket 5 2TB earns higher TBW ratings (1,400 vs 880 TBW) — relevant for sustained write workloads, irrelevant for everything else.
For PlayStation 5 builds, the console's internal M.2 slot tops out around 5,500 MB/s sustained, so both Sabrent Rocket 5 2TB and Crucial P310 2TB hit the same wall — pick whichever is cheaper at the moment you buy. The Gen 5 Sabrent Rocket 5 2TB 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 2TB'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 2TB nor Crucial P310 2TB fits without modification.
Market context: the Sabrent Rocket 5 2TB ranks #3 of 11 Gen 5 2 TB drives we track by $/TB, while the Crucial P310 2TB ranks #4 of 11 Gen 4 2 TB drives. One of them is genuinely among the cheapest options in its class, so this matchup includes a real value pick.
As of July 27, 2026, these tracked drives undercut both the Sabrent Rocket 5 2TB and Crucial P310 2TB on $/TB:
The Sabrent Rocket 5 2TB is the right call if meaningfully faster reads (14,000 MB/s), higher sustained writes (11,600 MB/s), a higher TBW endurance rating (1,400 TBW), and a dedicated DRAM cache chip matter to you. Sabrent's Rocket line carries a community reputation for transparent firmware support — manual update tools available directly from the manufacturer.
The Crucial P310 2TB is the right call if the lower retail price ($292 vs $350), and better $/TB economics ($146.00/TB) matter to you.
