Hard Disk MTBF: Flap or Farce?

"Data sheets for hard drives have always included a specification for reliability expressed in hours: commonly known as MTBF (mean time between failures), or sometimes the mean time to failure. Same difference: One way assumes that a drive will be fixed, and the other, replaced. Nowadays, this number is around a million hours for an 'enterprise' hard drive. Some drives are rated at 1.5 million hours."
