I'm looking for a good quality portable external hard drive that can store up to/ over 1 TB for under $150. I've heard that wd drives are not such good quality and have a warranty only for 1 year, and that brands like seagate are good quality with a longer warranty. I'm not sure which sites are the best deals, and so far i looked on newegg, amazon, and buy.com. Also I would like to have a good extended warranty for at least 3 years. Would anyone recommend I get a extended warranty from squaretrade or similar type (besides for the one with AMEX) ?
