One disk has a MTBF of 300,000 hours and another disk has a MTBF of 100,000 hours. If both cost the same and have the same functionality, which one is best?
300,000 hours
100,000 hours
The longer the MTBF, the longer the mean time to failure. So the one that lasts 300,000hrs is better than the one that lasts 100,000hrs.
