Hello, I have a new Santa Rosa MBP with a 160GB 7200rpm drive, and the standard ethernet 802.11n Airport Extreme Base Station. I am completely new to Macs and laptops, but not new to computers in general and have made a smooth, happy transition so far. Before I rip my CD library to iTunes, I wanted to arrange an external backup solution. I figure the initial backup will be done via the Firewire interface (FW800) directly connected to the MBP, and then nightly or weekly incremental backups can be done over my wireless network with the drive connected to either the ethernet or USB of the AEBS (anything that uses the USB is called an Airdisk?). My problem is, I have no idea which disk to buy. I know brands: I want to get a WD, Seagate or Lacie. I am fixed on that. But would a simple USB interface be quick enough for restoring/backing up movies and music on demand? How much extra cost is it to get something with FW800 and ethernet interfaces (usually I just see things with FW and USB, not ethernet)? What is the minimum speed interface I would need to do photo editing or music/movie playing from the external drive, and would this be possible over 802.11n? Do I need any special software to ensure I can smoothly restore my iTunes library if Mac OS X is reinstalled on my MBP, or will simple backups of the music files be fine? What specific models would fit my needs? I am looking in the 250-500GB size range. I am particularly interested in hearing from other people with MBPs and AEBS setups, but would welcome any advice... I read a couple other ext. drive threads in the forum, but none of them completely answered my questions Thanks!
