IOMeter 4KB Random Performance

Our 4KB random performance test is conducted in the same manner as our sequential tests, but once the drive is conditioned we run our saved random test profile that runs our 4KB test for two minutes without any idle time in between the tests. The queue depth is set to 32 on four workers and the test is begun. To get the benefits from NVMe based drives you must use multiple CPU queues and this is why we are now using four workers for this IOMeter test.

4k-iops

IOPS is the main thing we are looking at in this test scenario and the Kingston UV400 480GB SSD is rated at 90k IOPS for the 4K Random Read and 50,000 IOPS for the 4K Random Write. Our testing showed that we were only able to get 76,295 IOPS read and 35,409 IOPS write on our pre-filled drive right after a secure erase was complete.

4k-mbps

When it comes to MBps you are looking at 313MB/s on the 4KB Random Reads and 145 MB/s on the 4KB Random writes for the Kingston UV400 480GB SSD.

4k-ms

The write response times on the Kingston UV400 480GB drive were better than the OCZ Trion 150, OCZ Trion 100 and Crucial BX200 drives.
