I always thought target USB on the N5200, as implemented, seemed pretty pointless. You could allocate some space from your array to be accessible as a USB hard drive. Pretty silly for a NAS. Especially since it was completely separate from your shares.
However, I now potentially see a use for it. With some limitations, my dvd player can play .avi files from USB hard drives. So in theory, if I create a target USB, format it as fat32 and put files on it, I can connect the NAS via USB to my DVD player and play .avi files. A de-facto media server.
Now the big question, is there any way to put files onto the target USB over the network? With sshd access to the N5200, could I possibly mount the target USB and copy files onto it?
Anybody doing anything like this?
