Which is better, Samsung 9100 PRO 4TB or Crucial T705 4TB? May 2026 side-by-side with prices, specs, and verdict.
A like-for-like comparison: both drives target the same buyer segment at the same Gen 5 4 TB class. The interesting question becomes which manufacturer's implementation aged better.
Hardware-wise, the Samsung 9100 PRO 4TB runs on the proprietary Samsung Presto silicon found only in the 9100 PRO line. The Crucial T705 4TB pairs Phison's E26 silicon, which kicked off the consumer Gen 5 era and typically requires a heatsink.
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 Crucial T705 4TB wins this matchup on $/TB. 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 Crucial T705 4TB fits without modification.
Among consumer SSD makers, Samsung's PRO series consistently scores highest on long-term reliability surveys (Backblaze, Puget Systems Q1 2026 data).
Lean toward the Crucial T705 4TB when the lower retail price ($749 vs $769), and better $/TB economics ($187.25/TB) top your priority list. Crucial's T-series tends to undercut Samsung and WD on price while using comparable Micron silicon — a value play hiding in a flagship form factor.
