Customers are replacing disk drives at rates far higher than those suggested by the estimated mean time to failure (MTTF) supplied by drive vendors, according to a study of about 100,000 drives conducted by Carnegie Mellon University.
This is something I’ve thought about before. Most drives are said to have an MTTF of one million hours, but how many people do you know who’ve had their hard drive die? I think I would have a harder time finding a person who hasn’t had that happen.
