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.

The part I’ve been waiting for, and all I can say is WOW! All three 830 models (yes, even the 64GB) literally walked over the competition in our IOPS testing. The only place they fell behind was at QD>16 on the Web Server test, and even then all three of them were nipping at the heels of the SandForce driven Intel SSD 520 Series. Most important to desktop and even power users is the fact that regardless of workload, at the ‘normal’ range of QD 1-8, Samsung beats everyone else hands down (and outright embarrasses its 470 Series predecessor). I expect to see some extremely low latencies on the next page.

Light desktop usage sees QD figures between 1 and 4. Heavy / power user loads run at 8 and higher. Most SSD’s are not capable of effectively handling anything higher than QD=32, which explains the plateaus.
