Samsung 9100 PRO 4TB ($769) vs Sabrent Rocket 5 4TB ($739). $/TB analysis, performance, and use-case recommendations.
Samsung 9100 PRO 4TB and Sabrent Rocket 5 4TB are direct competitors — same generation, same capacity. Choose by controller behavior under sustained load, DRAM/HMB cache strategy, and $/TB economics.
Hardware-wise, the Samsung 9100 PRO 4TB runs on the proprietary Samsung Presto silicon found only in the 9100 PRO line. The Sabrent Rocket 5 4TB pairs Phison's E26 silicon, which kicked off the consumer Gen 5 era and typically requires a heatsink.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (14,000 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the Sabrent Rocket 5 4TB. For content creators routinely rendering 4K or 8K video, the Samsung 9100 PRO 4TB's 13,400 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 Samsung 9100 PRO 4TB nor Sabrent Rocket 5 4TB fits without modification.
The Samsung 9100 PRO 4TB is the right call if higher sustained writes (13,400 MB/s) matter to you. Among consumer SSD makers, Samsung's PRO series consistently scores highest on long-term reliability surveys (Backblaze, Puget Systems Q1 2026 data).
The Sabrent Rocket 5 4TB is the right call if the lower retail price ($739 vs $769), and better $/TB economics ($184.75/TB) 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.
