The main reason I suspect is covered below, but the only time this is a useful thing is dual booting - the rest of the time network attached storage is the 'right' answer. Personally, I'm glad to have left the time of dual booting operating systems behind me - it's a complete PITA. A Linux box with a bunch of disks under samba/ext4/lvm/mdadm is much more practical IMHO.
