Here are my results with a PATA drive and a SATA drive:
[root@poontang ~]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 172 MB in 3.02 seconds = 56.97 MB/sec
[root@poontang ~]# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 300 MB in 3.01 seconds = 99.66 MB/sec
Your results are similar to what I get with my PATA drive, so I agree
with Ho Chaw Ming that you should check that AHCI is selected.
