Depending on the motherboard / chipset
hdparm -d1 /dev/hda is the common flag
Here is a snip from this machine
/dev/hdb:
Timing buffer-cache reads: 128 MB in 1.68 seconds =76.19 MB/sec
Timing buffered disk reads: 64 MB in 3.29 seconds =19.45 MB/sec
We have others on the bench with 150 MB/sec buffer-cache and disk reads of 26
MB/sec
