Firstly, ensure that you have the tool – apt-get install hdparm
Once done, quite simply use hdparm with -t or -T options to time buffered reads and cache reads respectively. Be VERY careful about other options that hdparm offers, some are very dangerous and can completely corrupt your data.
apnic03:~# hdparm -t /dev/sda

Timing buffered disk reads: 200 MB in 3.00 seconds = 66.57 MB/sec
apnic03:~# hdparm -T /dev/sda

Timing cached reads: 4372 MB in 2.00 seconds = 2187.38 MB/sec
