Compare WD_BLACK SN850X 1TB and Crucial T500 1TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both the WD_BLACK SN850X 1TB and Crucial T500 1TB sit in the Gen 4 category at 1 TB, so the matchup turns on controller efficiency, cache topology, and current pricing rather than raw class differences.
Hardware-wise, the WD_BLACK SN850X 1TB runs on WD's second-generation G2 in-house controller, tuned for sustained gaming I/O. The Crucial T500 1TB pairs Phison's E25 silicon, found in many DRAM-equipped Gen 4 SSDs.
For PlayStation 5 builds, the console's internal M.2 slot tops out around 5,500 MB/s sustained, so both WD_BLACK SN850X 1TB and Crucial T500 1TB hit the same wall — pick whichever is cheaper at the moment you buy. 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.
The SN850X has been the best-selling Gen 4 NVMe in PCPartPicker builds for two consecutive years — Game Mode 2.0 prioritizes I/O when supported titles need it.
Pick the Crucial T500 1TB if you value the lower retail price ($115 vs $119), and better $/TB economics ($115.00/TB). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
