I need half a terrabit of hdd to complete my dvd/cd collection. My mobo has four ide (one used for dvd) and a pair of ATA's, does this mean that I can have 5 hdd's? Any issues with assign one as the boot device? I've seen some external firewire, ethernet or USB2 hdd as well, which are getting alot cheaper. Which is better, excluding raid for the moment. Externals will allow movement of LARGE files, but cost is an option aswell.
