Kingston DC400 480GB SSD Review

Kingston quote a random write figure of 11,000 IOPS when the drive is in a steady state. Under test conditions, the drive reached this figure at a queue depth of 4 but struggled to reach that level at higher and indeed lower queue depths.

The drive's sustained random write performance isn't as consistent as its random read performance, peaking at 44.85MB/s at a queue depth of 4.

When it comes to comparing the drive's random write performance against block size at a queue depth of 256 the drive displays a good level of consistency at higher block sizes.

Once again the emphasis is on low to moderate queue depths.
