Side-by-side: Crucial T710 1TB ($264) vs WD Blue SN5100 1TB ($180). $/TB winner, specs, real-world picks for September 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 SMI's SM2508 silicon, which became the default Gen 5 controller for power-conscious flagships. The WD Blue SN5100 1TB pairs the SanDisk controller.
Money matters here — $180.00/TB on the WD Blue SN5100 1TB versus $264.00/TB on the Crucial T710 1TB. That's enough of a spread that for budget-conscious builders, the WD Blue SN5100 1TB becomes the default unless reviews of your specific workload prefer the Crucial T710 1TB.
On sequential reads the Crucial T710 1TB pulls ahead by 8,300 MB/s (14,900 MB/s versus 6,600 MB/s). That matters for moving large files but rarely shows up in game loads.
Write speeds skew toward the Crucial T710 1TB: 12,000 MB/s sustained against 5,400 MB/s. Content creators feel this; gamers do not.
The DRAM-vs-HMB question divides opinion: Crucial T710 1TB's on-board DRAM theoretically helps under sustained workloads, while WD Blue SN5100 1TB's HMB approach has matured enough that most users won't see the difference. Pick on price if everything else is similar.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Crucial T710 1TB and WD Blue SN5100 1TB to roughly equal in-game load times. The cheaper drive is the smart pick. 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 Blue SN5100 1TB pairing: only for sustained sequential reads of multi-GB files. Video editors will gravitate toward the Crucial T710 1TB for its write headroom (12,000 MB/s sustained). Project saves and proxies move faster, which compounds across a workday. 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: the Crucial T710 1TB ranks #6 of 6 Gen 5 1 TB drives we track by $/TB, while the WD Blue SN5100 1TB ranks #1 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.
At $180.00/TB, the WD Blue SN5100 1TB is already among the cheapest 1 TB drives we track — nothing in this class undercuts it. See the full $/TB ranking.
Go with the Crucial T710 1TB for meaningfully faster reads (14,900 MB/s), higher sustained writes (12,000 MB/s), and a dedicated DRAM cache chip. 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.
Go with the WD Blue SN5100 1TB for the lower retail price ($180 vs $264), and better $/TB economics ($180.00/TB).
