  I thought these are about to be expected (DMA on hd* disks, the sda 
disk is SATA, the hd* are IDE)), do you get different speed on SATA

jojda:/home/erik# hdparm -t /dev/sda1

/dev/sda1:
 Timing buffered disk reads:  156 MB in  3.00 seconds =  52.00 MB/sec
jojda:/home/erik# hdparm -t /dev/hda

/dev/hda:
 Timing buffered disk reads:   26 MB in  3.08 seconds =   8.44 MB/sec
jojda:/home/erik# hdparm -t /dev/hdb

/dev/hdb:
 Timing buffered disk reads:   74 MB in  3.00 seconds =  24.67 MB/sec
