Compare WD_BLACK SN8100 2TB and TeamGroup MP44L 2TB: prices, speeds, $/TB. Which to buy in September 2026? Full spec breakdown.
WD_BLACK SN8100 2TB vs TeamGroup MP44L 2TB pits two different generations against each other at 2 TB. The question isn't which is faster on paper — that's settled — it's whether the bandwidth gap shows up in your specific workload.
Hardware-wise, the WD_BLACK SN8100 2TB runs on an SMI SM2508 controller that drew industry attention in 2024 for finally taming Gen 5 thermals. The TeamGroup MP44L 2TB pairs a MAP1602 controller built specifically for DRAM-less HMB designs.
Price separates these two meaningfully. The TeamGroup MP44L 2TB costs $146.50/TB versus $220.00/TB for the WD_BLACK SN8100 2TB — a 33% premium that needs justification in real benchmarks, not just spec-sheet bragging.
In the read department, the WD_BLACK SN8100 2TB leads by roughly 9 GB/s. The difference is more academic than practical for typical use, but it does matter for video editors moving multi-GB project files.
Write performance separates them too. The WD_BLACK SN8100 2TB sustains 11,000 MB/s writes versus 4,500 MB/s for the TeamGroup MP44L 2TB — a real advantage for video editors and anyone doing heavy file operations.
The WD_BLACK SN8100 2TB carries a dedicated DRAM chip for FTL (Flash Translation Layer) mapping; the TeamGroup MP44L 2TB relies on HMB (Host Memory Buffer), borrowing 64 MB from system RAM. The practical gap shows up only under sustained random write loads.
Heading to a PlayStation 5? Both drives drop into the console's M.2 bay and report identical real-world benchmarks since the PS5 caps storage at PCIe 4.0 speeds. The TeamGroup MP44L 2TB wins this matchup on $/TB. The leap from Gen 4 to Gen 5 doubles peak throughput on paper but produces single-digit-percent improvements in game load times, OS boot, and most productivity benchmarks. The TeamGroup MP44L 2TB is the better default unless you have a specific workload that needs the extra lanes. For content creators routinely rendering 4K or 8K video, the WD_BLACK SN8100 2TB's 11,000 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 SN8100 2TB nor TeamGroup MP44L 2TB fits without modification.
Market context: the WD_BLACK SN8100 2TB ranks #9 of 11 Gen 5 2 TB drives we track by $/TB, while the TeamGroup MP44L 2TB ranks #2 of 11 Gen 4 2 TB drives. 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 September 7, 2026, these tracked drives undercut both the WD_BLACK SN8100 2TB and TeamGroup MP44L 2TB on $/TB:
Pick the WD_BLACK SN8100 2TB if you value meaningfully faster reads (14,900 MB/s), higher sustained writes (11,000 MB/s), and a dedicated DRAM cache chip.
Pick the TeamGroup MP44L 2TB if you value the lower retail price ($293 vs $440), and better $/TB economics ($146.50/TB). The TeamGroup MP44L 2TB 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.
