Indeed, lucky me. As of this moment I have 6 of 9650 in production boxes.
For at least 6 years. During which time none of them ever failed on me
(including any trouble with arrays). Knocking on wood. I must say though
that I do prefer the most reliable drives. And I always have arrays
checked at least once a week through 3ware scheduler (this causes walk
through the whole surface of each of drives, thus ensuring bad blocks if
any do not stay undiscovered...).
