Compare Crucial T705 2TB and TeamGroup Z540 2TB: prices, speeds, $/TB. Which to buy in May 2026? Full spec breakdown.
Both the Crucial T705 2TB and TeamGroup Z540 2TB sit in the Gen 5 category at 2 TB, so the matchup turns on controller efficiency, cache topology, and current pricing rather than raw class differences.
There's a modest pricing advantage for the TeamGroup Z540 2TB: $164.50/TB compared with $199.50/TB. For typical gaming and productivity, this becomes the deciding factor when specs are close.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both Crucial T705 2TB and TeamGroup Z540 2TB to roughly equal in-game load times. The cheaper drive is the smart pick. For content creators routinely rendering 4K or 8K video, the Crucial T705 2TB's 12,700 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 Crucial T705 2TB nor TeamGroup Z540 2TB fits without modification.
Pick the Crucial T705 2TB if you value meaningfully faster reads (14,500 MB/s). Crucial typically delivers the best $/TB among DRAM-equipped NVMes because Micron sells direct rather than going through brand licensing.
Pick the TeamGroup Z540 2TB if you value the lower retail price ($329 vs $399), and better $/TB economics ($164.50/TB). The TeamGroup Z540 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.
