Side-by-side: WD_BLACK SN7100 2TB ($290) vs Crucial T500 2TB ($369). $/TB winner, specs, real-world picks for July 2026.
Gen 4 at 2 TB is one of the most contested SSD segments in 2026, and WD_BLACK SN7100 2TB versus Crucial T500 2TB captures that competition well. The decision rarely comes down to peak speeds — both drives saturate typical workloads.
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 2TB pairs an E25 controller that became the workhorse of late Gen 4 designs.
Prices favor the WD_BLACK SN7100 2TB by $39.50/TB ($145.00/TB versus $184.50/TB). Not a huge gap, but enough to be the tiebreaker if performance is similar.
The DRAM-vs-HMB question divides opinion: Crucial T500 2TB's on-board DRAM theoretically helps under sustained workloads, while WD_BLACK SN7100 2TB's HMB approach has matured enough that most users won't see the difference. Pick on price if everything else is similar.
For PlayStation 5 builds, the console's internal M.2 slot tops out around 5,500 MB/s sustained, so both WD_BLACK SN7100 2TB and Crucial T500 2TB hit the same wall — pick whichever is cheaper at the moment you buy. 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 2TB fits without modification.
Zoom out from this pair for a moment. Among the 11 Gen 4 2 TB drives we track, the WD_BLACK SN7100 2TB ranks #3 by $/TB and the Crucial T500 2TB ranks #9. 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 WD_BLACK SN7100 2TB and Crucial T500 2TB on $/TB:
Go with the WD_BLACK SN7100 2TB for the lower retail price ($290 vs $369), and better $/TB economics ($145.00/TB).
Go with the Crucial T500 2TB for 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.
