Compare Sabrent Rocket 5 4TB and Samsung 990 PRO 4TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Sabrent Rocket 5 4TB vs Samsung 990 PRO 4TB pits two different generations against each other at 4 TB. The question isn't which is faster on paper — that's settled — it's whether the bandwidth gap shows up in your specific workload.
Hardware-wise, the Sabrent Rocket 5 4TB runs on the Phison E26 — the first widely-deployed Gen 5 controller, capable but thermally demanding. The Samsung 990 PRO 4TB pairs the in-house Samsung Pascal — engineered specifically for the 990 PRO at 8nm.
Price separates these two meaningfully. The Samsung 990 PRO 4TB costs $97.25/TB versus $184.75/TB for the Sabrent Rocket 5 4TB — a 47% premium that needs justification in real benchmarks, not just spec-sheet bragging.
Read speeds favor the Sabrent Rocket 5 4TB: 14,000 MB/s versus 7,450 MB/s for the Samsung 990 PRO 4TB, a 47% advantage. Sequential-heavy workloads notice; transactional workloads don't.
The Sabrent Rocket 5 4TB writes about 41% faster (11,600 MB/s vs 6,900 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.
Heading to a PlayStation 5? Both drives drop into the console's M.2 bay and report identical real-world benchmarks since the PS5 caps storage at PCIe 4.0 speeds. The Samsung 990 PRO 4TB wins this matchup on $/TB. The leap from Gen 4 to Gen 5 doubles peak throughput on paper but produces single-digit-percent improvements in game load times, OS boot, and most productivity benchmarks. The Samsung 990 PRO 4TB is the better default unless you have a specific workload that needs the extra lanes. 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.
Pick the Sabrent Rocket 5 4TB if you value meaningfully faster reads (14,000 MB/s), and higher sustained writes (11,600 MB/s). Sabrent extends Rocket warranties to 5 years through manufacturer registration and ships with the latest Phison firmware revisions, often ahead of competitors.
Pick the Samsung 990 PRO 4TB if you value the lower retail price ($389 vs $739), and better $/TB economics ($97.25/TB). Among consumer SSD makers, Samsung's PRO series consistently scores highest on long-term reliability surveys (Backblaze, Puget Systems Q1 2026 data).
