The memory of the Deathstar drives that stands out most in my mind was a coworker managing to destroy hardware with SQL. We were at a really ... frugal ... interactive advertising firm and our dev server had been slapped together with a RAID-1 array of cheap IBM drives. One day said coworker was testing conversion of a large database table in MySQL from MyISAM to InnoDB format (to see how long it'd take, what query perf afterwards was like, etc.) and all of a sudden the server went hard down. We went over to the server closet and discovered that the IO had been enough for both drives to grenade themselves at the same time. Good times. I'm just glad we had semi-decent backups and it wasn't a production machine.
