Which is better, Samsung 9100 PRO 4TB or Crucial T705 4TB? July 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.
At a 32% price gap, the Samsung 9100 PRO 4TB needs to be measurably better in your specific use case to justify the spend. For gaming and general PC use, the Crucial T705 4TB's lower $/TB tilts the value equation decisively in its favor.
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.
Zoom out from this pair for a moment. Among the 6 Gen 5 4 TB drives we track, the Samsung 9100 PRO 4TB ranks #5 by $/TB and the Crucial T705 4TB ranks #2. That puts at least one of them near the top of the value table — a reasonable head-to-head to be choosing from.
As of July 27, 2026, these tracked drives undercut both the Samsung 9100 PRO 4TB and Crucial T705 4TB on $/TB:
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 ($613 vs $898), and better $/TB economics ($153.25/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.
