Need some advice. I want to have wireless backup and network storage to keep mostly my iTunes library on. I want to be able to use it with a Mac and a PC. I can buy an Apple Time Capsule for $300. I can then plug an external 2tb hard drive (which I already have) into the USB to allow me to backup the time capsule so I have a backup of my data. OR, I can buy a Synology 2-bay NAS from Amazon with two 2tb hard drives for about $430. What should I do? I realize that in order to, say, stream movies from the storage device to my Apple TV, I will still need to have a computer running iTunes on the network, which is fine. I got a rMBP and am looking for an external solution, and something where I don't have to plug in an external hard drive all the time. I don't need to be able to access the files remotely. I just need to be able to get to them from my local network. I'd prefer the lower cost of the Time Capsule, but want to be sure that it will do what I need it to do efficiently. Note: I also already have an N router at home, which is pretty much brand new, so I don't NEED the router features of the Time Capsule, though I'd use it if I had one.
