Kingston SSDNow KC400 512GB SSD Review

Rating: 8.0.

Kingston's SSDNow KC400 family is part of the company's business-oriented SSD product line which features end-to-end data path protection, technologies to protect data in the NAND and guard against read errors, as well as good endurance.

The SSDNow KC400 uses a combination of an 8-channel Phison PS3110-S10 controller and 15nm MLC NAND. There are four capacities in the product line; 128GB, 256GB, 512GB and the flagship 1TB drive. Kingston quote performance figures for the 512GB version of up to 550MB/s for sequential reads and up to 530MB/s for sequential writes. Random 4K performance is quoted as up to 86,000 IOPS for reads and 88,000 IOPS writes.


To underline its suitability for the business sector, the KC400 has end-to-end data path protection and a couple of other data protection technologies; SmartECC protects data from being corrupted, while SmartRefresh protects against read errors – the data is rebuilt should an error occur. If the system experiences an unexpected power loss then there is power loss management built into the firmware.

Endurance for the 512GB drive is quoted as 800TB TBW and Kingston back the KC400 line with a five-year warranty.
