SSD Performance IO Meter IOPS

 

IO Meter IOPS performance

New in our tests is IO meter. We brought the ancient application back in rotation as it remains to be the best application to really stress the Random IO performance amongst others of 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 3 minutes and then note down the average IOPS score in operations per second.

First off read performance. We have very few results as this is a recently added application. If you look at the top tfour, really good performance. These are SandForce products known and reputed exactly because of that performance. The Enyo is exactly where it should be performance wise though.

Now with Random IO 4KB WRITE performance here again is EXACTLY where the SandForce controllers kick massive ass, Random IO writes. Both the Corsair P128 (Samsung controller) and original Vertex (Indilinx) run into roughly 2000 operations per second.  All the way at the bottom we see the Silicon Power M10 SSD with JMicron controller (no cache memory) merely 500 write IOPS/sec.

Being Indilinx based, the Enyo actually manages to keep up with the competition, but obviously is nowhere close to the SandForce based products.
