SSD Performance Iometer

Iometer IOPS Performance

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

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/Os per second, Iometer is set to use 4 KB file size chunks and will completely trash the SSD with random 4 KB files, massively stressing the random IO.

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