The IOMeter benchmark 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.

Overall, the IOPS delivered by the MX300 SSD were not the highest we have seen, in both read and write tasks. Again, a decent performance that could be higher, as Crucial' previous MX200 SSD performed better here:
