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 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.

…and here we see that firmware really is everything when it comes to mixed mode performance of an SSD. The stock SandForce firmware just doesn’t hold a candle to those coming out of Intel and OCZ. The Intel 320 series SSD was able to perform better here, despite being bottlenecked by its 3Gb/sec interface bandwidth.
