I am considering purchasing a Airport BSE. I currently have a D-link DIR-655. To begin with, most of the time, my Macbook Pro won't pick up the external HD that I have connected to the router because the Dlink SharePoint software is terrible. Secondly, when it does work, the performance is terrible. I'd say it is probably worse than half the speed of plugging the drive directly into the MBP. Now I realize there will be a performance degradation when attaching an external HD to the ABSE, but my question is, how much are we talking? A percentage terms (rough estimate is fine) would be the best. Like, lets say it takes 30 seconds to transfer a 1gb file when the external HD is connected directly into my MBP via USB (hypothetical, it probably takes longer) how long would you guess would it take when its over the network? Additionally, can an Xbox 360 or PS3 read from the HD over the network?
