Teste com  "hdparm":

[root@li1145-165 ~]# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   13910 MB in  2.00 seconds = 6968.29 MB/sec
 Timing buffered disk reads: 3490 MB in  3.00 seconds = 1163.15 MB/sec
[root@li1145-165 ~]# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   12702 MB in  2.00 seconds = 6363.15 MB/sec
 Timing buffered disk reads: 6008 MB in  3.00 seconds = 2001.79 MB/sec
[root@li1145-165 ~]# hdparm -tT /dev/sda
