Still using those old Hard Disks? I would highly recommend that you switch to SSDs if you’re a mildly tempered person.

Well anyway, here’s a tip for everyone who hasn’t made the jump to solid state: try to be nice to your disk drive. Brendan Gregg from Sun’s Fishworks team wanted to see the effects of vibrations on his disk array, so he proceeded to shout at it. On video. Yeah, we bet that’s pretty embarrassing for the drive in question, and what results is a sharp spike the number of I/O operations that take over 5ms to complete. Moral of the story? Yelling at your computer isn’t going to make it run any faster. How about next time we see how it reacts to Ozzy, Mozart and warm, gentle nuzzles?
