Samsumg 160GB 5krpm, quite silent with acoustic management, no problem
at all (well one problem, but I guess that's the ext3 -T largefile
problem not related to the drive: takes long to delete large files)


myth:~# hdparm -tT /dev/hda

/dev/hda:
 Timing buffer-cache reads:   240 MB in  2.02 seconds = 118.81 MB/sec
 Timing buffered disk reads:   98 MB in  3.00 seconds =  32.67 MB/sec
myth:~# hdparm -I /dev/hda
