So I am wanting to buy or build an external harddrive. Any opinions on buy vs. build? As far as brands if I was going to buy one, I was leaning towards Western Digital or Seagate. It seems like all of the harddrive reviews on newegg.com have at least a few people saying the drive is awful and died within months, or just after the warranty period. A lot of people online suggest buying an external enclosure and an internal harddrive. I am confident I could figure this out. I am curious though, many people suggesting that say that you don't need a power source if you go this way, how does this work? thanks y'all!
