[Linux] 在linux下測試硬碟速度

首先要先用df找出你要測試哪一個分割, ex:

Filesystem            Size  Used Avail Use% Mounted on
/dev/sda3             140G   98G   36G  74% /
/dev/sda1              99M   34M   60M  37% /boot
tmpfs                 2.0G     0  2.0G   0% /dev/shm

例如是/dev/sda3, 然後就輸入下列指令

hdparm -tT /dev/sda3

等一會應該就會有簡易的結果如下

/dev/sda3:
 Timing cached reads:   31484 MB in  2.00 seconds = 15781.22 MB/sec
 Timing buffered disk reads:  310 MB in  3.01 seconds = 102.90 MB/sec
