The MTBF for the disk is given as 1000000 hours, while most other disks I've seen are around the 750000/800000 hour mark. This server runs in a cupboard in a factory though and runs significantly hotter than room temperature and every time I work on it I end up covered in dirt, but this is the first disk failure after around 3 years of hard use.
There are not many hours in a year, so 3 years is little compared to 10^6 hours. (That 114 year MTBF is quite impressive.) It does though halve for each 10°C rise above the temperature at which the lifetime is predicted. (The vendor hasn't run his drives for 114 years for the prediction. Running at 80°C above nominal for 6 months is equivalent to 128 years of life.)

"Because ants taking the shorter path travel faster, the amount of pheromone (or light) deposited on that path grows faster, so more ants use that path." - http://www.bbc.co.uk/news/21956795
