Compare WD_BLACK SN850X 1TB and Crucial T500 1TB: prices, speeds, $/TB. Which to buy in July 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 G2 controller — manufactured by SanDisk and tuned for low-latency gaming workloads. The Crucial T500 1TB pairs the Phison E25 — a refined Gen 4 controller widely used in mid-range NVMe drives.
There's a modest pricing advantage for the WD_BLACK SN850X 1TB: $220.00/TB compared with $275.00/TB. For typical gaming and productivity, this becomes the deciding factor when specs are close.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (7,300 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the WD_BLACK SN850X 1TB. Heads-up — these are full-length 2280 drives. Steam Deck and most current handhelds require shorter 2230 modules, so check capacity-specific 2230 variants if that's your target platform.
Market context: we track 4 Gen 4 1 TB drives, and by price per terabyte the WD_BLACK SN850X 1TB currently sits #2 while the Crucial T500 1TB sits #4. Neither is a value leader right now — if $/TB is your priority, check the cheaper alternatives below before committing.
As of July 27, 2026, these tracked drives undercut both the WD_BLACK SN850X 1TB and Crucial T500 1TB on $/TB:
Pick the WD_BLACK SN850X 1TB if you value the lower retail price ($220 vs $275), and better $/TB economics ($220.00/TB). Among Gen 4 flagships, the SN850X strikes a sweet spot — premium silicon at sub-Samsung pricing, with WD's established RMA process to back it up.
Crucial drives benefit from being a direct Micron product — the same NAND that powers competitors' drives, but at lower margins.
