IOMeter v2006.07.27 – IOps
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation and announced at the Intel Developers Forum (IDF) on February 17, 1998 – since then it got wide spread within the industry.
Meanwhile Intel has discontinued to work on Iometer and it was given to the Open Source Development Lab (OSDL). In November 2001, a project was registered at SourceForge.net and an initial drop was provided. Since the relaunch in February 2003, the project is driven by an international group of individuals who are continuesly improving, porting and extend the product.
That did improve our results and allow the Apex 250GB SSD to give us “normal” testing scores. That being said, there is something amiss with this application and this particular drive as no other HDD or SSD has exhibited any similar results. I am going to continue looking into the incompatibility with IOMeter in the coming weeks hoping to find the culprit and thus be sure there is nothing wrong with the JMicron-based internal RAID architecture design.
Anyway, on to the results we do have: the file server and web server results still show the Intel X25-M with a large advantage in IOs per second though the Apex drive does well enough to stand out with or from the other SSD drives tested. In the database and workstation results the Apex drive does much better overtaking the Intel drive with larger queue depths on the database test and leading the entire time under the workstation results.
