Samsung 990 PRO 1TB ($135) vs Crucial P310 2TB ($155). $/TB analysis, performance, and use-case recommendations.
Both run on Gen 4 hardware but at different capacities: 1 TB for the Samsung 990 PRO 1TB versus 2 TB for the Crucial P310 2TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
Hardware-wise, the Samsung 990 PRO 1TB runs on the in-house Samsung Pascal — engineered specifically for the 990 PRO at 8nm. The Crucial P310 2TB pairs an E27T controller built specifically for DRAM-less Gen 4 SSDs.
The cost difference is hard to ignore: 43% per TB (Crucial P310 2TB at $77.50/TB versus Samsung 990 PRO 1TB at $135.00/TB). Unless you specifically need the Samsung 990 PRO 1TB's peak performance, the Crucial P310 2TB delivers more storage for the money.
Cache architecture differs: Samsung 990 PRO 1TB has DRAM hardware, Crucial P310 2TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
Crucial P310 2TB earns higher TBW ratings (880 vs 600 TBW) — relevant for sustained write workloads, irrelevant for everything else.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (7,100 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the Crucial P310 2TB. For content creators routinely rendering 4K or 8K video, the Samsung 990 PRO 1TB's 6,900 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 990 PRO 1TB nor Crucial P310 2TB fits without modification.
The Samsung 990 PRO 1TB is the right call if the lower retail price ($135 vs $155), and a dedicated DRAM cache chip matter to you. Among consumer SSD makers, Samsung's PRO series consistently scores highest on long-term reliability surveys (Backblaze, Puget Systems Q1 2026 data).
The Crucial P310 2TB is the right call if better $/TB economics ($77.50/TB), and a higher TBW endurance rating (880 TBW) matter to you.
