I'm thinking of getting a Drobo for a back-up solution and for my iTunes/iPhoto/Aperture Library. I convert a lot of my movies through Handbrake with the AppleTV preset. Is a Drobo connected to my iMac via USB 2.0 have enough bandwidth to watch on my HDTV? The setup will be... Drobo > USB 2.0 > iMac > Wifi (G) > Router > Wired (100) > Apple TV With that setup, will I run into any lag when watching a Movie on my HDTV? Thanks in advance.
