SSD Performance IOMeter


IO Meter IOPS performance

IO meter, results vary per website since everybody configures this test differently. We brought the ancient application back in rotation as it remains the best application to really stress the random IO performance amongst others for storage devices.

OCZ Vertex 3 PRO review

Iometer is a workload creator, it will literally perform massive I/O operations in order to stress the system. To measure random I/O response time as well as total I/O's per second, Iometer is set to use 4KB file size chunks and will completely trash the SSD with random 4KB files, massively stressing the random IO.

We apply a 4KB Random IO read and write stress test, leave it running for a while and then note down the average IOPS score in operations per second.

OCZ Vertex 4 with v1.5 Firmware

Above read performance, we ran it three times to be sure and time after time the v1.5 firmware release gave us a big perf increase in read IO, nice.

 OCZ Vertex 4 with v1.5 Firmware 

Above write performance - again a small overall increase.
