    Can I connect it directly to computer by using Ethernet cable with out router or switch hub?
    Asked by: Hsiu P.
    It's designed to be a network device, connected to a router and has internet connection (for updated, download packages and other functionality) it's probably possible to connect directly to a computer with a cross over Ethernet cable and a PC with 2 Ethernet ports, but it would be much simpler getting a switch or connecting to your cable modem

    Can I only use 2 of the bays initially? To start I will only be able I afford 2 hard drives, but in the future will need all 4.
    Asked by: John B.
    Yes you can add two hard drives initially and add further at a later stage. Thats what I did as I didnt have 4 either. This depends mainly on the type of RAID configuration you wish to have.
