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's become wide spread within the storage industry.
We use Iometer to measure disk response times. Disk response times are measured at an industry accepted standard of 4K QD1 for both write, and read. Each test is run twice, for 30 seconds consecutively, with a five second ramp-up before each test. The drive/array is partitioned and attached as a secondary device for this testing.
Average Disk Response
Write response times benefit most from RAID 0 because of write caching. There is a slight latency increase in read response times for an array vs. a single drive. The Chronos array has slightly faster write response times than the SuperSSpeed array; however, the SuperSSpeed array has vastly superior read response times in comparison to the Chronos array.
