i'm getting tired of burning cd/dvd for backup, and had the thought that i might be better off with a modest external hard drive, e.g. 10/20 gb. i only want to backup iPhoto, iTunes, and a couple other folders that tend to change consistently, and i really think external hd is the better path. but i'm not really knowledgeable and thought i would ask for comments on my thoughts in general, and specifically some recommendations on exernal hd. thanks
