Compare WD_BLACK SN8100 4TB and Crucial T710 2TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both run on Gen 5 hardware but at different capacities: 4 TB for the WD_BLACK SN8100 4TB versus 2 TB for the Crucial T710 2TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
WD_BLACK SN8100 4TB earns higher TBW ratings (2,400 vs 1,200 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 (14,500 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the WD_BLACK SN8100 4TB. For content creators routinely rendering 4K or 8K video, the Crucial T710 2TB's 14,000 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 WD_BLACK SN8100 4TB nor Crucial T710 2TB fits without modification.
Pick the WD_BLACK SN8100 4TB if you value better $/TB economics ($207.25/TB), and a higher TBW endurance rating (2,400 TBW).
Pick the Crucial T710 2TB if you value the lower retail price ($449 vs $829), and higher sustained writes (14,000 MB/s). 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.
