Hello everyone!

As a photographer without a lot of money, my girlfriend used external drives to backup her files. A few years ago, she was able to upgrade to two 8tb WD My Book: one that she uses on a day to day basis, the other as an exact copy (thank's SuperDuper!).

But we now want to upgrade to a NAS. Since we will need a lots of storage (I was thinking four 8tb drives, so that we can have a few tb each with redundancy), I was wondering if I could use the drives inside the My Book in our NAS?

I could just open it, but I don't want to ruin her hd before we buy our NAS, and I can't find any reliable info about what's inside. I'm sure there are some reliability issue in using used hd in a NAS, I'm just curious.
