I see a lot of variation in this kind of thing. Copying a big
backup file to my external usb hard driver made my system stutter
a bit (though nothing like what you describe), but I have recently
dd'ed up some disk images for xen, and the system worked perfectly
well during that operation.

This was on fedora 8 x86_64 with sata disks.
