I have just ordered a new AEBS for my home network for the intention of connecting an external HDD to use as NAS. I am rocking a new i5 MBA SSD, a 2010 15" i5 MBP, [as well as other tech] and I will be using a 7200rpm 2.5" external HDD attached to the AEBS. Has anyone used a similar setup, if so how quick were transfer speeds? I want to migrate me iTunes/iPhoto/iMovie libraries onto the external HDD and connect via wifi from the MBA. Thanks.
