Hard Drives Fail, A Reminder

This email greeted me yesterday morning:

One of the drives in the server that runs Startupping had failed. No data was lost, because the drive was part of a RAID. The hosting company was able to quickly replace it and things are back to normal. But it serves as a reminder that hard drives are not nearly as reliable as most people think they are. You need to always plan for failure because it will happen.
