Side-by-side: WD_BLACK SN7100 2TB ($305) vs Crucial T500 2TB ($390). $/TB winner, specs, real-world picks for September 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 $42.50/TB ($152.50/TB versus $195.00/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 #6 by $/TB and the Crucial T500 2TB ranks #9. Neither cracks the top of the value table, so it's worth glancing at the alternatives below before picking either.
As of September 7, 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 ($305 vs $390), and better $/TB economics ($152.50/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.
