My wife and I have a ton of DVDs and CDs and I've been going through them (tagging, encoding, etc.). Now, my WD MyBook 1TB is filled and I have another 2 TB to complete the rest of my collection. I had another MyBook for video folders but it failed several weeks ago. So I'm thinking of either building a machine of buying a NAS. What would be the best NAS brand to go with? I have a good budget so any help would be appreciated.
