Which is better, Crucial P310 2TB or WD Blue SN5100 1TB? July 2026 side-by-side with prices, specs, and verdict.
Both run on Gen 4 hardware but at different capacities: 2 TB for the Crucial P310 2TB versus 1 TB for the WD Blue SN5100 1TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
Hardware-wise, the Crucial P310 2TB runs on the DRAM-less Phison E27T, common in value-tier 2TB and 4TB Gen 4 drives. The WD Blue SN5100 1TB pairs the SanDisk controller.
Crucial P310 2TB's $146.00/TB pricing edges out WD Blue SN5100 1TB's $182.00/TB by about 20%. Not transformative, but a real difference at 2-4 TB capacities where it adds up.
On warranty endurance the Crucial P310 2TB carries 880 TBW against WD Blue SN5100 1TB's 600 TBW. Both will outlast typical use, but the gap matters if you're doing professional content work.
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 Crucial P310 2TB and WD Blue SN5100 1TB as interchangeable here and let price decide. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Crucial P310 2TB's 6,000 MB/s sustained write speed. Both drives use the 2280 form factor, which is too long for Steam Deck or ROG Ally — you'd need a 2230 variant if either manufacturer offers one, or a dedicated handheld-format drive instead.
Market context: the Crucial P310 2TB ranks #4 of 11 Gen 4 2 TB drives we track by $/TB, while the WD Blue SN5100 1TB ranks #1 of 4 Gen 4 1 TB drives. That puts at least one of them near the top of the value table — a reasonable head-to-head to be choosing from.
Lean toward the Crucial P310 2TB when better $/TB economics ($146.00/TB), and a higher TBW endurance rating (880 TBW) top your priority list.
Lean toward the WD Blue SN5100 1TB when the lower retail price ($182 vs $292) top your priority list.
