KingSpec 1TB 2.5 SSD SATA III Internal

Bottom line: The KingSpec 1TB 2.5 SSD SATA III Internal: 550MB/s read and 520MB/s write saturate the SATA III 6Gb/s interface; main trade-off: SATA III caps throughput far below NVMe M.2 drives in the same price range.

Pros & Cons

Pros

  • ✓ 3-year limited warranty plus lifetime technical support from KingSpec

Cons

  • ✗ SATA III caps throughput far below NVMe M.2 drives in the same price range
  • ✗ No mounting bracket, SATA cable, or cloning software listed in the box
  • ✗ Over-provisioning reduces usable capacity below the advertised 1TB
  • ✗ 2.5-inch bay required - will not fit M.2-only thin laptops or mini PCs

Manufacturer description

The KingSpec 1TB 2.5" SATA III SSD is a straightforward drop-in upgrade for any laptop, desktop, or all-in-one still booting from a mechanical hard drive. Built on 3D NAND flash, it hits sequential reads up to 550MB/s and writes up to 520MB/s over the SATA Rev. 3.0 (6Gb/s) interface, which is effectively the ceiling of what SATA allows - so boot times, application launches, and large file transfers all tighten up noticeably compared to a spinning disk. KingSpec includes the controller features that keep a drive healthy over years of use: wear leveling, garbage collection, over-provisioning…
