That's called a NAS or NAS BOX. There are hundreds of those out there.
Ok, I've got a few external HDs (500s/250s) I'd like to simply set them up as drives on my network where anyone in the family can access them wirelessly. I've seen wireless hubs, but they hook up to one computer only. My Cisco router has one USB but that allows for only one drive (it won't read a hub attached HD). Is there a simple solution out there?
I guess I'm looking for a USB hub that I could plug into my router with a CAT5 and still be able to differiantiate the drives. Am I crazy?
