I had 10 out of 12 go bad on my freenas box a few years ago, will NEVER buy seagate drives again.
I've been using seagate drives exclusively for the past 8 years with no unusual failures. I will always buy seagate. </anotherpointlessanecdote>
All drives fail, catastrophically, at the worst time. More important than "will it fail or not?" (because they all fail) is "how good are the warranties?", "how good is the customer service?", and "have we tested our backups?"
