CLI tool to benchmark drive performance

Project description

Designed to run similar tests as Crystal Disk Mark using fio with user friendly output options.

Tests ran:

  • Sequential read/write w/ 1MB block size

  • Random read/write w/ 512K block size

  • Queue depth 32 random read/write 4K blocks size


# system install
$ sudo pip3 install disk-bench

# user install
$ pip3 install --user disk-bench


$ disk-bench --help

# Default runs fio w/ --loops=3 and --size=1G
$ disk-bench /mnt/disk-to-test/whatever

# Show CSV output (for easy copy/paste into Excel or Google Sheets)
$ disk-bench /mnt/disk-to-test/whatever --style=csv

# Quick
$ disk-bench /mnt/disk-to-test/whatever --loops=1 --size=1M
