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:
/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
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:
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
Bonnie
Per effettuare dei benchmark sui dischi, è possibile utilizzare anche Bonnie++.
