Which is better, WD_BLACK SN7100 4TB or TeamGroup MP44 4TB? July 2026 side-by-side with prices, specs, and verdict.
A like-for-like comparison: both drives target the same buyer segment at the same Gen 4 4 TB class. The interesting question becomes which manufacturer's implementation aged better.
Hardware-wise, the WD_BLACK SN7100 4TB runs on SanDisk's A101 controller, used in newer WD_BLACK SKUs after the SanDisk spinoff. The TeamGroup MP44 4TB pairs a MAP1602 controller built specifically for DRAM-less HMB designs.
TeamGroup MP44 4TB's $128.25/TB pricing edges out WD_BLACK SN7100 4TB's $142.50/TB by about 10%. Not transformative, but a real difference at 2-4 TB capacities where it adds up.
For PlayStation 5 builds, the console's internal M.2 slot tops out around 5,500 MB/s sustained, so both WD_BLACK SN7100 4TB and TeamGroup MP44 4TB hit the same wall — pick whichever is cheaper at the moment you buy. For content creators routinely rendering 4K or 8K video, the WD_BLACK SN7100 4TB's 6,700 MB/s sustained write is the deciding factor — multi-GB project files land noticeably faster than on the alternative. 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 4TB nor TeamGroup MP44 4TB fits without modification.
Zoom out from this pair for a moment. Among the 6 Gen 4 4 TB drives we track, the WD_BLACK SN7100 4TB ranks #5 by $/TB and the TeamGroup MP44 4TB ranks #2. That puts at least one of them near the top of the value table — a reasonable head-to-head to be choosing from.
As of July 27, 2026, these tracked drives undercut both the WD_BLACK SN7100 4TB and TeamGroup MP44 4TB on $/TB:
The WD_BLACK SN7100 4TB fits buyers who prefer its specific performance profile or have brand preference for WD.
Lean toward the TeamGroup MP44 4TB when the lower retail price ($513 vs $570), and better $/TB economics ($128.25/TB) top your priority list. The TeamGroup MP44 4TB captures the value tier well: same NAND class as flagships, paired with a DRAM-less controller that costs less and uses HMB for the address-mapping table.
