1. many topics on this, search is key
2. since we're here.. they're all the same.. some people have great luck with each brand
personally i own over 30 wd and about 15 maxtors and 3-4 seagate.. at once time or another, all 3 brand has been rmaed at least 3-4 times. Just last week was 2 WD (over 2 year old) and 1 seagate (over 2 year old). Right now, Seagate has the 5 year warranty.. so I would get them.. not sure if all seagate models carry 5 year.. need to check on that
