Compare TeamGroup MP44 4TB and Lexar NM790 4TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both the TeamGroup MP44 4TB and Lexar NM790 4TB sit in the Gen 4 category at 4 TB, so the matchup turns on controller efficiency, cache topology, and current pricing rather than raw class differences.
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 Lexar NM790 4TB wins this matchup on $/TB. Both drives use the 2280 form factor, which is too long for Steam Deck or ROG Ally — you'd need a 2230 variant if either manufacturer offers one, or a dedicated handheld-format drive instead.
The TeamGroup MP44 4TB wins on $/TB because it pairs DRAM-less MAP1602 silicon with low-margin distribution. Performance is fine for OS and gaming, weaker only on sustained random writes.
Pick the Lexar NM790 4TB if you value the lower retail price ($269 vs $279), and better $/TB economics ($67.25/TB). Budget-tier drives like the Lexar NM790 4TB have closed the gap with premium NVMes — the MAP1602 controller is genuinely competitive for everyday workloads at half the price.
