I'm in the market to purchase two 1TB drives to run in a RAID-1 configuration for data backup (music, videos, photos, etc.). I'm stuck between the Caviar Black WD1001FALS and the Caviar Green WD10EADS. I understand that the black is faster, runs hotter, and has a 5 year warranty. The green is a bit slower (not sure if that will make a difference in my case), cooler, but only has a 3 year warranty. Any advice?
