Status: Timetec 512GB SSD 3D NAND SATA III 6Gb/s M.2… (512GB NVMe SSD): Unavailable on Amazon as of . Closest in-stock match (same 512GB NVMe): Timetec 512GB SSD NVMe PCIe Gen3x4 8Gb/s M.2…, $78.99 on Amazon as of 2026-10-20 16:23 UTC (price may vary). eBay sellers may still list this model new or used.

Bottom line: The Timetec 512GB SSD 3D NAND SATA III 6Gb/s M.2 2280 NGFF 256TBW Read: 550MB/s read and 500MB/s write saturates the SATA III 6Gb/s ceiling; main trade-off: M.2 SATA, not NVMe, so it caps at roughly one-seventh of PCIe 4.0 speeds.

Pros & Cons

Pros

  • ✓ 550MB/s read and 500MB/s write saturates the SATA III 6Gb/s ceiling
  • ✓ 256TBW endurance rating on 512GB of 3D NAND
  • ✓ 1,500,000-hour MTBF, an industry-leading figure for this class
  • ✓ SLC cache absorbs write bursts during large game installs and file copies

Cons

  • ✗ M.2 SATA, not NVMe, so it caps at roughly one-seventh of PCIe 4.0 speeds
  • ✗ No mounting screw, bracket, or cable included in the box
  • ✗ Requires an M.2 slot wired for SATA; NVMe-only slots will not detect it
  • ✗ 512GB fills fast if you install modern 100GB+ game titles

Manufacturer description

The Timetec 512GB M.2 2280 SATA III SSD is a straightforward storage upgrade for any desktop or laptop with a spare M.2 slot wired for SATA. It reaches sequential reads up to 550MB/s and writes up to 500MB/s, saturating the SATA III 6Gb/s interface, and an SLC cache layer absorbs bursts of writes so large file copies and game installs hold their pace instead of collapsing partway through. The 3D NAND inside is rated for 256TBW and an industry-leading 1,500,000-hour MTBF, so you can treat this Timetec drive as a daily boot volume rather than a scratch disk. Firmware handles the housekeeping…

SpecPicks Verdict

SpecPicks scored Timetec 512GB SSD 3D NAND SATA III 6Gb/s M.2 2280 NGFF 256TBW Read… using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Timetec's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for ssds & storage of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

Is this an NVMe drive or a SATA drive?

It is M.2 2280 SATA III 6Gb/s, not NVMe. Your motherboard's M.2 slot must support SATA mode. Read speeds top out at 550MB/s and writes at 500MB/s, which is the SATA III ceiling.

Will it work in my laptop?

It fits any desktop or laptop with an M.2 2280 slot that accepts SATA III 6Gb/s. It is also backwards compatible with SATA II 3Gb/s and SATA I 1.5Gb/s hosts.

How long will this SSD last?

It carries a 256TBW endurance rating and a 1,500,000-hour mean time before failure. Wear leveling and garbage collection run in firmware to spread writes across the 3D NAND.

Does it come with mounting screws or a cable?

No. The package contains the M.2 2280 SSD only. All cables, screws, and brackets are not included, so source the standoff screw from your motherboard kit.

Which operating systems can I install on it?

Windows 11, 10, 8.1, 8, and 7 are supported, along with Linux kernel 2.6.33 or later. S.M.A.R.T., TRIM, ECC, and RAID support are handled at the firmware level.
