I tried to setup a new NAS yesterday. The biggest problem was getting new HDDs.

On Amazon, I am only allowed to buy 1 HDD, lol.

Okay then. Ordered it and drove to a local electronics market. They had exactly 1 (non NAS) HDD. Ok I bought it. Now I got 2 HDDs and I had to look up my old crap to harvest 2 more old HDDs to get this thing up and running.. it's really hard nowadays to get more storage at home.
