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.

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 which became a standard, we leave it running for a while and then note down the average IOPS score in operations per second.

Above Corsair Neutron WRITE

Above Corsair Neutron GTX WRITE

Corsair advertises that with 4K aligned files these SSDs should be fast, and yes sir it really is. It will get even more bizarre though, have a peek at write performance:

Above write performance - that's right, we pass 84K IOPS on writes as advertised for the Neutron with the GTX closing in on 90K IOPS, that just boggles the mind really.
