= hdparm command =

You can use the hdparm command to check hard disk speed. It provides a command line interface to various hard disk ioctls supported by the stock Linux ATA/IDE/SATA device driver subsystem. Login as the root and enter the following command:

[root@server2 ~]# hdparm -tT /dev/sda

Sample outputs:
<code>
/dev/sda:
Timing cached reads: 29084 MB in 2.00 seconds = 14574.71 MB/sec
Timing buffered disk reads: 308 MB in 3.01 seconds = 102.36 MB/sec
Note:
-t :perform device read timings
-T :perform cache read timings
/dev/sda : Hard disk device file
</code>
= dd Command =

You can use the dd command as follows to get speed info too:

[root@server2 ~]# dd if=/dev/zero of=/tmp/test.img bs=8k count=256k
[root@server2 ~]# rm /tmp/test.img

Sample outputs:
<code>
dd: writing `/tmp/test.img': No space left on device
210779+0 records in
210778+0 records out
1726697472 bytes (1.7 GB) copied, 22.3398 seconds, 77.3 MB/s
