ok, so here is what I am looking to do. Currently i have a macbook air and use an external hard drive to store my music, pictures, movies, etc. I do not like having to constantly attach my external hard drive to the laptop (it is not very convenient and not very portable). I would like to have my external hard drive attached to my wi-fi network so i no longer have to physically plug it into my computer. I currently have a wi-fi router but it does not have a place to plug in a USB hard drive. It is my understanding i could use an airport extreme in place of my wi-fi router and attach my hard drive to it to access my files via the network..... is this correct? is this the best option or does anybody have any other recommendations? thanks for the help!
