Compare WD_BLACK SN850X 1TB and Crucial T500 2TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both run on Gen 4 hardware but at different capacities: 1 TB for the WD_BLACK SN850X 1TB versus 2 TB for the Crucial T500 2TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
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 2TB pairs Phison's E25 silicon, found in many DRAM-equipped Gen 4 SSDs.
There's a modest pricing advantage for the Crucial T500 2TB: $94.50/TB compared with $119.00/TB. For typical gaming and productivity, this becomes the deciding factor when specs are close.
On warranty endurance the Crucial T500 2TB carries 1,200 TBW against WD_BLACK SN850X 1TB's 600 TBW. Both will outlast typical use, but the gap matters if you're doing professional content work.
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 2TB hit the same wall — pick whichever is cheaper at the moment you buy. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Crucial T500 2TB's 7,000 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.
Pick the WD_BLACK SN850X 1TB if you value the lower retail price ($119 vs $189). 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 2TB if you value better $/TB economics ($94.50/TB), and a higher TBW endurance rating (1,200 TBW). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
