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.
Above the IOMeter READ performance on 4 KB aligned files. It's writes what we are interested in really:
We apply a 4KB Random IO write stress test so it differs a little from OCZ's own test methodology, we leave it running for a while and then show the average IOPS score in operations per second.
Above write performance - Now with Random IO 4KB WRITE performance, this is where SandForce controllers feel themselves rather groovy. It seems that everybody is using IOMeter's parameters slightly different, but that is more than I initially expected for a Hybrid storage solution.
IOmeter is a test that is ideal to show high numbers IOPS for SSD technology and take it for granted as such. The results disappointed a little bit, but then again ... it's prolly 100x better then just a HDD could ever accomplish.
