I'm looking to add a 1TB drive to my Time Capsule to use for accessing files (the internal drive is used for Time Machine). I'm deciding between the MyBook Essential Edition, MyBook Studio Edition and the Iomega Prestige. I was wondering if anybody had any thoughts between those three. The MB Essential and Prestige are about the same price and about $50 cheaper than the Studio Edition. The Studio has Firewire which won't matter connected to the TC but might be nice if I ever hook it up direct. Any thoughts would be appreciated.
