Anybody here uses a Seagate ST320413A with UDMA enabled on Linux?
I can't seem to get anything better than 5.x from hdparm tests
compared with a Samsung drive.  I've already tried upgrading the
firmware, interchanging the cables and drives but still no luck.
Any tips?

# hdparm -tT /dev/hda /dev/hdc

/dev/hda:
 Timing buffer-cache reads:   128 MB in  3.16 seconds = 40.51 MB/sec
 Timing buffered disk reads:  64 MB in 11.84 seconds =  5.41 MB/sec

/dev/hdc:
 Timing buffer-cache reads:   128 MB in  3.12 seconds = 41.03 MB/sec
 Timing buffered disk reads:  64 MB in  5.17 seconds = 12.38 MB/sec

# dmesg | grep 'hd[a|c]: '
