WD_BLACK SN7100 2TB ($290) vs Crucial T500 1TB ($275). $/TB analysis, performance, and use-case recommendations.
Both run on Gen 4 hardware but at different capacities: 2 TB for the WD_BLACK SN7100 2TB versus 1 TB for the Crucial T500 1TB. Whether the larger drive's $/TB advantage justifies the higher upfront cost depends on how much you actually need.
Hardware-wise, the WD_BLACK SN7100 2TB runs on SanDisk's A101 controller, used in newer WD_BLACK SKUs after the SanDisk spinoff. The Crucial T500 1TB pairs an E25 controller that became the workhorse of late Gen 4 designs.
The cost difference is hard to ignore: 47% per TB (WD_BLACK SN7100 2TB at $145.00/TB versus Crucial T500 1TB at $275.00/TB). Unless you specifically need the Crucial T500 1TB's peak performance, the WD_BLACK SN7100 2TB delivers more storage for the money.
Cache architecture differs: Crucial T500 1TB has DRAM hardware, WD_BLACK SN7100 2TB uses HMB. For OS, gaming, browsing — indistinguishable. For databases, large file ops, or 4K video editing — DRAM has a small but consistent edge.
WD_BLACK SN7100 2TB earns higher TBW ratings (1,200 vs 600 TBW) — relevant for sustained write workloads, irrelevant for everything else.
For PS5 expansion, both are PCIe Gen 4 M.2 2280 drives that meet Sony's minimum spec (7,250 MB/s read). The console can't take advantage of speeds beyond that, so save money by choosing the WD_BLACK SN7100 2TB. Note for handheld gamers: M.2 2280 is the desktop/laptop standard. Steam Deck and the ROG Ally line need 2230 drives — neither WD_BLACK SN7100 2TB nor Crucial T500 1TB fits without modification.
Market context: the WD_BLACK SN7100 2TB ranks #3 of 11 Gen 4 2 TB drives we track by $/TB, while the Crucial T500 1TB ranks #4 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.
The WD_BLACK SN7100 2TB is the right call if better $/TB economics ($145.00/TB), and a higher TBW endurance rating (1,200 TBW) matter to you.
The Crucial T500 1TB is the right call if the lower retail price ($275 vs $290), and a dedicated DRAM cache chip matter to you. 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.
