Ran the tests, here are the results. gentoo ~ # hdparm -tT /dev/hda /dev/hda: Timing cached reads: 1916 MB in 2.00 seconds = 957.71 MB/sec Timing buffered disk reads: 4 MB in 3.87 seconds = 1.03 MB/sec gentoo ~ # hdparm -tT /dev/hdb /dev/hdb: Timing cached reads: 1764 MB in 2.00 seconds = 881.48 MB/sec Timing buffered disk reads: 4 MB in 3.87 seconds = 1.03 MB/sec Looks like the second disk (hdb) is slightly slower for cached reads. Could it be because of the shared IDE cable ? thanks Saifi.
