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 our own 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 kick massive ass. The latest 1.2 model kicks ass when it comes to IOPS perf alright.
We apply our own 4KB Random IO read and write stress test so it differes a little from OCZ's own test methodology, we leave it running for a while and then note down the average IOPS score in operations per second.
Above read performance - again really good performance right there. Roughly 72K IOPS which is fantastic. The CPU usage was a little high during this test (Core i7 2600K processor), but this test is so immense it could kill off a mid-range system really.
Above write performance - Now with Random IO 4KB WRITE performance, this is where SandForce controllers kick massive ass. It seems that everybody is using IOMeter's parameters slightly different, but that is more than I expected.
Also and I really need to say this, we feel IOMeter is just a horrible test. There's no application in this world that continuously writes perfect 4K files all of the time. The test was designed to show high numbers for SSD technology and as such we start to dislike it more and more, as it does not say a thing about actual real-world performance. What this test needs in order to become more objective is random file/block sizes while reading and writing.
