No, just backing up my music that at the moment is on a few smaller drives.
I don't think I am going to need more until the time comes to back up all the music that I am in the process of ripping. I have two 2 TB internal drives for this and will probably need another two more I think to back it all up.
However, I will also need the help of an FM soon enough as the music server I have only takes two internal drives - which I have already in use. And eventually I will need 4 2TB drives for my music. So will have to build a more comprehensive seamless storage system. The good thing is it does not play directly but off an SDD - so when building a playlist all the selected albums need to be copied from the storage drive to the SDD.
