I've searched both here on MacRumors forum, and on the internet in general, but never found a solid answer as to how many drives an airport extreme can handle. I know that Apple states that it is possible to attach a USB hub, allowing the connection of printers and multiple drives - but is there a limit as to how many drives that can be attached? I am looking to attach a printer and four external drives. Currently I have them attached to my iMac, and I have network shares setup to allow connections from an Apple TV, MacBook Pro and an HP PC. I would prefer to be able to shutdown/reboot my iMac without having to worry about knocking the other devices off of the internet. I am also temporarily using my iMac to provide wireless internet for both the Apple TV and the MacBook - but I would prefer to utilize the improved security offered by the Airport Extreme (WPA/hidden SSD). The Airport Extreme seems like it would be a perfect addition to the home network, though I just want to make sure that I don't spend the extra money on the Airport Extreme, open and set it up, only to find out that it can't easily handle four external drives plus a printer. I'm curious to find out how many drives forum members here have been able to successfully attach and share through their Airport Extreme.
