So I have a 500gb Lacie external drive, and Im looking to get a 1TB one as well, and Im interested to see where people would steer me to? I am mostly going to use it to back up my iTunes and iPhoto, and TM my MB and iMac. I was thinking about a Time Capsule, but is it that much better for the obvious difference in price? I am sure that the backup over the air is a nice feature, but like I said, is it worth the price? I was also looking at the WD 1TB My Book, and a G-Tech 1TB SATA drive. Any opinions? Also, I have Google'd the following question, but I was hoping someone to explain the following like you would to your mother: What is RAID and would that benefit me? Thanks for the help!
