Pick DiskMark if…

DiskMark may suit Windows users who want a small utility for assessing disk performance with configurable test options. Its separate 32-bit and 64-bit downloads may be relevant when selecting an executable.

Pick fio if…

fio suits people who need to define and run storage I/O workloads without writing a separate test program for each one. Its client/server mode may be useful when jobs need to run on remote hosts.
