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.
Our four different configuration of IOMeter show that in terms of raw I/O operations per second the new Raptor X is a fantastic performer, though it can’t quite topple the 74 GB Raptor in our tests. Both of the 10k RPM Raptor drives though have a significantly higher score than the 7200 RPM drives.
IOMeter is also reporting that in our tests the Raptor X is nearly as fast as the 74 GB Raptor in terms of total time per transaction with varying queue depths. As the depth increases so does the gap between the 10k RPM drives and the 7200 RPM drives.
