Is your feature request related to a problem? Please describe.
By default, dd uses a very low I/O queue depth, so it is difficult to ensure that the benchmark is generating a sufficient number of I/Os and bytes to accurately test disk performance.

Additionally, special devices used with dd are often very slow and do not accurately reflect disk performance. In general, it's recommended to avoid using special devices such as /dev/urandom, /dev/random, and /dev/zero in disk performance benchmarks.

Describe the solution you'd like
To benchmark disk performance, use FIO instead of dd

Additional context
Espacially true when running in a virtualized environment where dd behave extremely bad compared to fio
