Which is better, Samsung 9100 PRO 2TB or Samsung 990 PRO 2TB? July 2026 side-by-side with prices, specs, and verdict.
Cross-generation comparisons reveal whether you're paying for peak speed or sustained value. Samsung 9100 PRO 2TB vs Samsung 990 PRO 2TB at 2 TB is a perfect lens for that question.
Hardware-wise, the Samsung 9100 PRO 2TB runs on the proprietary Samsung Presto silicon found only in the 9100 PRO line. The Samsung 990 PRO 2TB pairs Samsung's Pascal controller, fabricated on the company's 8nm process.
In the read department, the Samsung 9100 PRO 2TB leads by roughly 7 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 Samsung 9100 PRO 2TB sustains 13,400 MB/s writes versus 6,900 MB/s for the Samsung 990 PRO 2TB — a real advantage for video editors and anyone doing heavy file operations.
PS5 owners get no measurable benefit from either drive's peak speed because Sony's internal NVMe controller throttles to ~5,500 MB/s; treat Samsung 9100 PRO 2TB and Samsung 990 PRO 2TB as interchangeable here and let price decide. Generational difference matters mainly for sequential-heavy workloads. The Samsung 9100 PRO 2TB's 14,700 MB/s read beats Samsung 990 PRO 2TB's 7,450 on paper, though in practice both feel identical loading games. For content creators routinely rendering 4K or 8K video, the Samsung 9100 PRO 2TB'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 2TB nor Samsung 990 PRO 2TB fits without modification.
