SSD Performance IOMeter | AS SSD Benchmark

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, leave it running for 1 minute and then note down the average IOPS score in operations per second.

Above is the write performance - Now with Random IO 4KB WRITE performance, this is where the SandForce controllers hauls massive ass. Our test  differs a little from the regular (OCZ) test methodology you see used mostly, we leave it running for a while and then note down the average IOPS score in operations per second.

Above read performance

Above write performance - Now with Random IO 4KB WRITE performance, this is where SandForce controllers kick in hard. It seems that most users are using IOMeter's parameters slightly different.

Also and I really need to say this, there's no application in this world that continuously writes perfect 4K files all of the time. The test is ideal to show high numbers IOPS for SSD technology and as such we start to dislike it more and more. That said, do with it as you please.
