USAFRet :
It's not a mii-NAS, it would be just another drive letter.
But yes...multiple drives are very, very common.
My main PC has 5
My HTPC/house server has 6
What I mean is that I would be able to use it on other computers in the house.
File and folder sharing. Configurable in the OS.
Basically, you share out a folder. Give permissions to "Everyone".
This is how my HTPC is configured. I can access the designated shared folders from whichever PC or device I want.
On my main PC, the "M" drive is actually the Movies folder, living on a drive on the other PC.
The "X" drive letter is music.
Etc, etc.
