I'm running Ubuntu 12.10, my wife has a mac and all the other computers are either older versions of Ubuntu and or Windows.

I would like to buy a (or two) external HD's for backup, mainly for pictures etc... I would like the files accesible from the devices on the network.

I was thinking of getting two 1tb or 2tb HD's.

Is there a website or reference or someplace that I can get some help on this topic or pointers?
