Linuxでfioを使用して簡易ディスクベンチマーク！

【LinuxでもCrystalDiskMarkぽいディスクベンチマークしたい】に触発されてCrystalDiskMarkの各バージョンのデフォルト値でのベンチマークパラメータをfioで再現してみました。 是非お使いください。

使い方

コマンド一例：

$ curl -sS https://gist.githubusercontent.com/t-okkn/c805b95dde1c6b9a528d1e3095814ebd/raw/a2b19eee9415fafd47285b53d0a5ae73b338fe6e/fio-CrystalDiskMark_old.txt | tee ~/fio.txt

$ # 一覧で表示
$ FIO_TARGET=~/fio fio -f fio.txt --output-format=terse | awk -F ';' '{ speed = (($7+$48) * 1024) / 1000; unit = "KB/s"; if (speed >= 1000000) { speed = (speed / 1000000); unit = "GB/s" } else if (speed >= 1000) { speed = (speed / 1000); unit = "MB/s" }; printf "%-22s %.3f %s\n", $3, speed, unit }'
