Bonnie

直接執行 Bonnie 就可以測試, 但不知道為什麼測試大小空間一定要 RAM * 2 的以上. 所以反而沒法很快的拿到測試結果

iozone

Iozone 有預設 13 種 pattern , 所以算是測試很齊全又不會太麻煩的工具
官網:
http://www.iozone.org/
使用方式介紹:

fio

fio 則是擁有全功能, 可以自己設計 pattern, 又很多參數可以調整, 是很專業的工具, 但要寫 Script, 如果想要快速的拿到一些 performance report, 可能不是很好用, 之前也有介紹過

ioping

https://code.google.com/p/ioping/
很簡易的工具, 支援 seq/random write, 也可以指定 block size, 可以很快速的可以得到大概的狀況.
