fio-cdm

Mimic CrystalDiskMark 6 on Linux devices with the help of fio

Tested with fio version 3.5

Usage

fio-cdm <path>

If using a custom build fio change FIOCMD to the absolute path of the fio binary.

Notes

Currently the following warning is emitted when running the script:

128K-Q32T1-Seq-Read: No I/O performed by libaio, perhaps try --debug=io option for details?
128K-Q32T1-Seq-Write: No I/O performed by libaio, perhaps try --debug=io option for details?

The results of the script seem to be correct but this should be investigated. This probably has something to do with the ramp_time option.

Sample

# fio-cdm /mnt/bc35
