Which is better, TeamGroup Z540 1TB or Crucial P510 1TB? 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 5 1 TB class. The interesting question becomes which manufacturer's implementation aged better.
Hardware-wise, the TeamGroup Z540 1TB runs on an original Phison E26 chip that defined the Gen 5 reference design. The Crucial P510 1TB pairs an E31T controller that trades DRAM for HMB to hit lower price points.
At a 41% price gap, the TeamGroup Z540 1TB needs to be measurably better in your specific use case to justify the spend. For gaming and general PC use, the Crucial P510 1TB's lower $/TB tilts the value equation decisively in its favor.
TeamGroup Z540 1TB bundles a DRAM cache chip; Crucial P510 1TB is DRAM-less. This sounds like a big deal but reviewers have been arguing for years about whether it actually matters in consumer use. For most workloads, no.
If this purchase is for a PS5 storage expansion, the comparison flattens — Sony's PCIe Gen 4 controller normalizes both TeamGroup Z540 1TB and Crucial P510 1TB to roughly equal in-game load times. The cheaper drive is the smart pick. For content creators routinely rendering 4K or 8K video, the TeamGroup Z540 1TB's 11,800 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 TeamGroup Z540 1TB nor Crucial P510 1TB fits without modification.
Zoom out from this pair for a moment. Among the 6 Gen 5 1 TB drives we track, the TeamGroup Z540 1TB ranks #6 by $/TB and the Crucial P510 1TB ranks #1. That puts at least one of them near the top of the value table — a reasonable head-to-head to be choosing from.
At $172.00/TB, the Crucial P510 1TB is already among the cheapest 1 TB drives we track — nothing in this class undercuts it. See the full $/TB ranking.
Lean toward the TeamGroup Z540 1TB when meaningfully faster reads (12,400 MB/s), higher sustained writes (11,800 MB/s), and a dedicated DRAM cache chip top your priority list. Budget-tier drives like the TeamGroup Z540 1TB have closed the gap with premium NVMes — the MAP1602 controller is genuinely competitive for everyday workloads at half the price.
Lean toward the Crucial P510 1TB when the lower retail price ($172 vs $290), and better $/TB economics ($172.00/TB) top your priority list.
