Checking Disk access time

1. using command:
hdparm -tT /dev/sda

sda being the device you want to check access speed of. The two speeds that appear as output are: 1. The speed of cache access. 2. The actual disk reads speed.


2. In case we need more description on device, fire:
 hdparm -I /dev/sda

Investigate hdparm --help for more options on disk eg. the drive geometry (-g)
