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 write performance - Now with Random IO 4KB WRITE performance, this is where SandForce controllers kick in hard.
Intel series 520 240GB SSD review
We review the Intel series 520 240GB SSD. They now have multiple SSDs on the market initially with their proprietary controller, then a Marvel controller, and today Intel releases the Series 520 SSDs based on SandForce, well LSI these days.
Intel series 320 SSD review
We review the Intel series 320 SSD. Armed with cheaper NAND flash memory this drive competes at the middle segment tagged with a decent price. But will it be enough to compete with the competition ?
