Side-by-side: TeamGroup Z540 2TB ($329) vs Crucial P310 2TB ($292). $/TB winner, specs, real-world picks for July 2026.
This is a generational matchup at 2 TB: the older-gen drive offers proven reliability and better $/TB, while the newer-gen sibling brings raw bandwidth that most users never tap.
Hardware-wise, the TeamGroup Z540 2TB runs on an original Phison E26 chip that defined the Gen 5 reference design. The Crucial P310 2TB pairs an E27T controller built specifically for DRAM-less Gen 4 SSDs.
Prices favor the Crucial P310 2TB by $18.50/TB ($146.00/TB versus $164.50/TB). Not a huge gap, but enough to be the tiebreaker if performance is similar.
In the read department, the TeamGroup Z540 2TB leads by roughly 5 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 TeamGroup Z540 2TB sustains 11,800 MB/s writes versus 6,000 MB/s for the Crucial P310 2TB — a real advantage for video editors and anyone doing heavy file operations.
The DRAM-vs-HMB question divides opinion: TeamGroup Z540 2TB's on-board DRAM theoretically helps under sustained workloads, while Crucial P310 2TB's HMB approach has matured enough that most users won't see the difference. Pick on price if everything else is similar.
TeamGroup Z540 2TB earns higher TBW ratings (1,400 vs 880 TBW) — relevant for sustained write workloads, irrelevant for everything else.
PS5 owners get no measurable benefit from either drive's peak speed because Sony's internal NVMe controller throttles to ~5,500 MB/s; treat TeamGroup Z540 2TB and Crucial P310 2TB as interchangeable here and let price decide. Comparing across generations always invites the same question: does the bandwidth gap convert into user-visible improvements? Honest answer for the TeamGroup Z540 2TB vs Crucial P310 2TB pairing: only for sustained sequential reads of multi-GB files. For content creators routinely rendering 4K or 8K video, the TeamGroup Z540 2TB'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 2TB nor Crucial P310 2TB fits without modification.
Market context: the TeamGroup Z540 2TB ranks #2 of 11 Gen 5 2 TB drives we track by $/TB, while the Crucial P310 2TB ranks #4 of 11 Gen 4 2 TB drives. One of them is genuinely among the cheapest options in its class, so this matchup includes a real value pick.
As of July 27, 2026, these tracked drives undercut both the TeamGroup Z540 2TB and Crucial P310 2TB on $/TB:
Go with the TeamGroup Z540 2TB for meaningfully faster reads (12,400 MB/s), higher sustained writes (11,800 MB/s), a higher TBW endurance rating (1,400 TBW), and a dedicated DRAM cache chip. Budget-tier drives like the TeamGroup Z540 2TB have closed the gap with premium NVMes — the MAP1602 controller is genuinely competitive for everyday workloads at half the price.
Go with the Crucial P310 2TB for the lower retail price ($292 vs $329), and better $/TB economics ($146.00/TB).
