Sabrent Rocket 5 4TB ($739) vs Crucial P310 4TB ($519). $/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 4TB runs on the Phison E26 — the first widely-deployed Gen 5 controller, capable but thermally demanding. The Crucial P310 4TB pairs Phison's E27T — a four-channel Gen 4 controller for HMB designs.
The cost difference is hard to ignore: 30% per TB (Crucial P310 4TB at $129.75/TB versus Sabrent Rocket 5 4TB at $184.75/TB). Unless you specifically need the Sabrent Rocket 5 4TB's peak performance, the Crucial P310 4TB delivers more storage for the money.
Read speeds favor the Sabrent Rocket 5 4TB: 14,000 MB/s versus 7,100 MB/s for the Crucial P310 4TB, a 49% advantage. Sequential-heavy workloads notice; transactional workloads don't.
The Sabrent Rocket 5 4TB writes about 48% faster (11,600 MB/s vs 6,000 MB/s). Whether that matters depends entirely on what you write to the drive — gameplay capture and large project saves benefit, browsing and gaming do not.
Cache architecture differs: Sabrent Rocket 5 4TB has DRAM hardware, Crucial P310 4TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
On warranty endurance the Sabrent Rocket 5 4TB carries 2,800 TBW against Crucial P310 4TB's 1,760 TBW. Both will outlast typical use, but the gap matters if you're doing professional content work.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Sabrent Rocket 5 4TB and Crucial P310 4TB to roughly equal in-game load times. The cheaper drive is the smart pick. The Gen 5 Sabrent Rocket 5 4TB 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. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Sabrent Rocket 5 4TB'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.
Market context: the Sabrent Rocket 5 4TB ranks #4 of 6 Gen 5 4 TB drives we track by $/TB, while the Crucial P310 4TB ranks #3 of 6 Gen 4 4 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 4TB and Crucial P310 4TB on $/TB:
The Sabrent Rocket 5 4TB is the right call if meaningfully faster reads (14,000 MB/s), higher sustained writes (11,600 MB/s), a higher TBW endurance rating (2,800 TBW), and a dedicated DRAM cache chip matter to you. Sabrent extends Rocket warranties to 5 years through manufacturer registration and ships with the latest Phison firmware revisions, often ahead of competitors.
The Crucial P310 4TB is the right call if the lower retail price ($519 vs $739), and better $/TB economics ($129.75/TB) matter to you.
