Side-by-side: Crucial T710 1TB ($227) vs WD_BLACK SN850X 1TB ($220). $/TB winner, specs, real-world picks for July 2026.
This is a generational matchup at 1 TB: the older-gen drive offers proven reliability and better $/TB, while the newer-gen sibling brings raw bandwidth that most users never tap.
Hardware-wise, the Crucial T710 1TB runs on the SMI SM2508 — a 6nm Gen 5 controller running notably cooler than first-gen Phison E26 designs. The WD_BLACK SN850X 1TB pairs the proprietary WD G2 silicon, optimized for the WD_BLACK line.
Read speeds favor the Crucial T710 1TB: 14,900 MB/s versus 7,300 MB/s for the WD_BLACK SN850X 1TB, a 51% advantage. Sequential-heavy workloads notice; transactional workloads don't.
The Crucial T710 1TB writes about 48% faster (12,000 MB/s vs 6,300 MB/s). Whether that matters depends entirely on what you write to the drive — gameplay capture and large project saves benefit, browsing and gaming do not.
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 T710 1TB and WD_BLACK SN850X 1TB as interchangeable here and let price decide. Comparing across generations always invites the same question: does the bandwidth gap convert into user-visible improvements? Honest answer for the Crucial T710 1TB vs WD_BLACK SN850X 1TB pairing: only for sustained sequential reads of multi-GB files. Heavy write workloads — video editing, RAW photo libraries, backup operations — favor the Crucial T710 1TB's 12,000 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 T710 1TB ranks #2 of 6 Gen 5 1 TB drives we track by $/TB, while the WD_BLACK SN850X 1TB ranks #2 of 4 Gen 4 1 TB drives. One of them is genuinely among the cheapest options in its class, so this matchup includes a real value pick.
As of July 27, 2026, these tracked drives undercut both the Crucial T710 1TB and WD_BLACK SN850X 1TB on $/TB:
Go with the Crucial T710 1TB for meaningfully faster reads (14,900 MB/s), and higher sustained writes (12,000 MB/s). Crucial drives benefit from being a direct Micron product — the same NAND that powers competitors' drives, but at lower margins.
Go with the WD_BLACK SN850X 1TB for the lower retail price ($220 vs $227), and better $/TB economics ($220.00/TB). WD_BLACK's SN850X earned its reputation through consistent sustained performance under gaming workloads — fewer micro-stutters during open-world streaming than budget alternatives.
