Verdict: Samsung 9100 PRO 4TB vs Crucial T705 4TB

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.

Real-world use cases

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.

Pick the Samsung 9100 PRO 4TB if...

Among consumer SSD makers, Samsung's PRO series consistently scores highest on long-term reliability surveys (Backblaze, Puget Systems Q1 2026 data).

Pick the Crucial T705 4TB if...

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.

Samsung 9100 PRO 4TB vs Crucial T705 4TB — common questions

What's the price difference between Samsung 9100 PRO 4TB and Crucial T705 4TB?

The Crucial T705 4TB costs $749 (187.25 per TB), while the Samsung 9100 PRO 4TB runs $769 (192.25 per TB). The gap is $20, equivalent to about 3% per TB. Prices change weekly; check current Amazon listings before deciding.

Does the Samsung 9100 PRO 4TB's read advantage matter in practice?

Specs say yes (14,800 MB/s versus 14,500 MB/s). Real-world testing says rarely. Game load times and OS boots saturate well below either drive's peak read speed. The advantage shows up in sustained sequential reads — large file copies, raw video reads, dataset loads.

Is the Samsung 9100 PRO 4TB or Crucial T705 4TB better for PS5?

Both are PCIe Gen 4 NVMe M.2 2280 — both meet Sony's expansion requirements. The PS5's M.2 controller caps sustained speeds at ~5,500 MB/s, so both drives saturate it equally. Pick on price — the Crucial T705 4TB at $187.25/TB is the better value. Add a heatsink (the PS5 cover provides minimal cooling) for thermal headroom.

Bottom line: Samsung 9100 PRO 4TB or Crucial T705 4TB?

Default recommendation: Crucial T705 4TB. It hits the right balance of price ($187.25/TB), Gen 5 performance, and brand support for the average buyer. The Samsung 9100 PRO 4TB has its place if you need higher sustained write speeds, but that's a narrower use case.
