I use a 20gb BUSlink external harddrive. Since I'm not someone that needs to burn cds for music or copying software to share with others, a cd burner wasn't much of a consideration when I was looking for a storage device. I'd also heard too many stories of cds being defective and so on. I'm very happy with the BUSlink and it's very sturdy. I do a nightly backup of my website and a backup of my graphics folders and sleep without worry.
