I am a little bit suspicious of using very large hard drives for backup/archiving. You can end up with all your eggs in one basket gone! I use a dual drive NAS in Raid 1 mirror mode for my archiving. If one drive goes down you can replace it and all your data is still intact.

Also since it is a network device you can access it's content from anywhere on your local network (or even further afield)if you wish. smile
