Sabrent Rocket 5 1TB ($259) vs WD Blue SN5100 1TB ($182). $/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 Phison's E26 silicon, which kicked off the consumer Gen 5 era and typically requires a heatsink. The WD Blue SN5100 1TB pairs the SanDisk controller.
The cost difference is hard to ignore: 30% per TB (WD Blue SN5100 1TB at $182.00/TB versus Sabrent Rocket 5 1TB at $259.00/TB). Unless you specifically need the Sabrent Rocket 5 1TB's peak performance, the WD Blue SN5100 1TB delivers more storage for the money.
On sequential reads the Sabrent Rocket 5 1TB pulls ahead by 7,400 MB/s (14,000 MB/s versus 6,600 MB/s). That matters for moving large files but rarely shows up in game loads.
Write speeds skew toward the Sabrent Rocket 5 1TB: 11,600 MB/s sustained against 5,400 MB/s. Content creators feel this; gamers do not.
Cache architecture differs: Sabrent Rocket 5 1TB has DRAM hardware, WD Blue SN5100 1TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Sabrent Rocket 5 1TB and WD Blue SN5100 1TB to roughly equal in-game load times. The cheaper drive is the smart pick. 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. Video editors will gravitate toward the Sabrent Rocket 5 1TB 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.
Market context: the Sabrent Rocket 5 1TB ranks #5 of 6 Gen 5 1 TB drives we track by $/TB, while the WD Blue SN5100 1TB ranks #1 of 4 Gen 4 1 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 1TB and WD Blue SN5100 1TB on $/TB:
The Sabrent Rocket 5 1TB is the right call if meaningfully faster reads (14,000 MB/s), higher sustained writes (11,600 MB/s), and a dedicated DRAM cache chip matter to you. Of the Phison E26 drives, Sabrent's Rocket 5 has earned a reputation for consistent thermal behavior with its larger heatsink design.
The WD Blue SN5100 1TB is the right call if the lower retail price ($182 vs $259), and better $/TB economics ($182.00/TB) matter to you.
