As above basically. Now that my media collection has grown, and I'm starting to take photos etc, I'm starting to worry about losing it all. At the moment, I have 4 2tb drives with various media on (TV, Films, photos, music, everything basically) And then a 128gb SSD for OS/programs So I thought I'd look into improving my storage situation, and am considering RAID, and whether that would be best for me. Ideally I'd like to keep it all in the one PC (having recently downsized to the single PC, works better for taking stuff to/from uni etc) I'm looking for something so I won't lose stuff if a drive dies or whatever, whether that be a straight backup, or some fancy RAID technology I've no idea. What would people suggest my next move be?
