Hey guys, I'm finally looking for an external HD to back-up my MBP and my home windows PC. I was thinking of getting a 500GB HD, I think that should be plenty. Now I'm not sure what to get, either a ready to go one like WD Passport vs. buying a case & HD. I was looking at this combo: Case: http://www.newegg.com/product/product.aspx?Item=N82E16817182123 HD: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136073 I'm not really looking to add a eSATA card, so to get MAX transfer speed I'm looking for a HD with Firewire 800 capabilities. I would like to get a very reliable drive as well. Finally what do you guys usually use to back-up files, just drag and drop files or Apple's Time Machine or another program. Also to be able to use this on my MBP and windows PC how should the HD be formatted? Thanks.
