This is the IOMeter benchmark. Iometer is run by using workstation and database patterns for queue depths (outstanding I/Os) representing very light and moderate loads. Iometer is both a workload generator (that is, it performs I/O operations in order to stress the system) and a measurement tool (that is, it examines and records the performance of its I/O operations and their impact on the system). The app's ability to bombard drives with an escalating number of concurrent IO requests also does a nice job of simulating the sort of demanding multi-user environments that are common in enterprise applications. The software can be used for measurement of the performance of an SSD. We started using the IOMeter tests using the Xtreme Benchmark template .
For the specific test, we used 100% random, 67%-33% Read/write distribution, aligned with the benchmarks we had already done in the past with other SSDs.
The Crucial M500 480GB SSD followed the OCZ Vertex 4 and the Vector SSDs in terms of IOPs, although it remains slower than them:
