Kingston SSDNow KC400 512GB

The Kingston SSDNow KC400 is a 2.5 inch internal solid state drive offering 512GB of storage capacity. It connects via a SATA 6Gb/s interface with backwards compatibility to SATA 3Gb/s and uses MLC memory components managed by a Phison 3110 controller.

Ideal for SATA laptop or desktop upgrades

This drive suits users upgrading a laptop or desktop that has a 2.5 inch SATA bay and wants faster boot and application loading than a mechanical hard disk. Systems limited to the older SATA 3Gb/s standard will still work but cannot reach the maximum transfer rates.

Sequential read up to 550 MB/s

The KC400 delivers sequential read speeds up to 550 MB/s and sequential write speeds up to 530 MB/s on the SATA 6Gb/s interface. Random 4k performance reaches up to 99,000 read IOPS and 86,000 write IOPS, which determines how quickly the drive handles small file operations.

Highlights

  • Fast boot and load times from up to 550 MB/s sequential read
  • Responsive multitasking with up to 99,000 IOPS 4K random read
  • Reliable sustained writes up to 530 MB/s sequential write
  • Proven MLC NAND paired with Phison 3110 controller for endurance
  • Fits standard 2.5" bays and runs 0 °C to 70 °C

Questions about this item

What connection does my motherboard need for the SATA Rev. 3.0 (6Gb/s) interface on this SKC400S37/512G drive?

A standard SATA data port and a SATA power connector from the PSU are required; the drive is backwards compatible with SATA Rev. 2.0 (3Gb/s) ports if your board only has those.

Will the Phison 3110 controller and MLC NAND work reliably alongside an older mechanical hard drive in the same system?

Yes, the drive operates independently on its own SATA port and power lead, so it adds 512 GB of solid-state speed without affecting the older drive's operation.

How can I verify the KC400 is delivering its rated 550 MB/s read and 530 MB/s write after installation?

Run a sequential benchmark such as CrystalDiskMark or AS SSD; the results should approach 550 MB/s read and 530 MB/s write on a SATA 6Gb/s link.
