Actually, I've never had a hard drive fail. I've always wanted to upgrade before it happened.

I recently got my hands on a Drobo for free. It is awesome. Literally a black box for storage, will scale well as disks get faster, and I'll always be buying disks at the optimal $/GB. The time saved in not thinking about it is awesome.

Having a hard-drive fail is a great experience. Only then will you forever change your habits on backup policies, redundancy and fail over.

Only the loss of something really value-able gives you that.
