Overview
KingSpec's USP3-1TB swaps a hard drive's spinning platters for 3D NAND flash in a standard 2.5 inch SATA III form factor, rated for 550 MB/s reads and 520 MB/s writes. It suits anyone replacing an aging hard drive or an older SATA SSD in a laptop or desktop.
This is a SATA III drive, not NVMe, so its real ceiling is the interface itself, near 550 MB/s, no matter how good the NAND inside is.
- 2.5 inch SATA III (6Gb/s), backward compatible with SATA II
- 3D NAND flash with TRIM, S.M.A.R.T, and garbage collection support
- Works with Windows 7 through 10/11, DOS, Linux, and Unix
- 3-year limited warranty with lifetime technical support claimed by the seller
Who it's for
Fits anyone upgrading a hard drive or a first-generation SATA SSD in a laptop or desktop who wants a faster, shock-resistant drive without paying for NVMe speeds they can't use. Not a fit for anyone with a free M.2 NVMe slot, since that interface clears SATA's ceiling entirely.
Pros and cons
- Sequential speeds up to 550/520 MB/s, well above a hard drive
- 1TB fits a full OS plus games or working files
- No moving parts, so no drop or vibration risk
- 3-year warranty per the manufacturer's spec sheet
- SATA III interface, not NVMe, so there's a real speed ceiling
- DRAM cache presence isn't stated anywhere in the spec sheet
Performance notes
SATA III caps throughput near 550/520 MB/s regardless of the NAND used, so this drive will boot and load programs far faster than a spinning disk but won't approach NVMe territory. The 3D NAND stacks memory cells vertically for density, and the spec sheet lists TRIM, wear leveling, over-provisioning, and S.M.A.R.T support to manage endurance over the drive's life. No moving parts also means the shock and vibration resistance the listing claims.

Frequently asked questions
Is the KingSpec USP3-1TB an NVMe drive?
