To save folks reading the entire PDF. My head still hurts! SMART status reports are not to be relied upon. 'Good' SMART status drives can still fail... High temperature and heavy usage are found not to correlate to failures. Infant (<3 months) and elderly (>5 years) drives appear to fail most. http://static.googleusercontent.com/external_content/untrusted_dlcp/research.google.com/en//archive/disk_failures.pdf

Certainly agree with the statement.....Infant (5 years) drives appear to fail most. I think the difference between makes is minor.

Seems to be the norm in my experience with most electronic items I purchase. It either craps out right away and you replace under warranty. Or it lasts a long time. Very little in between time failures. I think that is why extended warranties are not usually a good thing. If the item craps out early it is covered by the general warranty. If you get the extended warranty, and it craps out after 5 years or so, you would probably want to replace it anyway as technology will have past it several times over. Extended warranties = the company is betting it will last and you are betting it won't. Thanks Robert for sifting through all that information.

Suddenly I started thinking of MTBF (mean time between failures) and RAM ( reliability, availability, and maintainability) all terms I had hoped to never hear again. Sweat, sweat - trying to do RAM engineering studies and in my ancient days trying to schedule main frame computer times to run programs. I need a drink

 I thought that bath tub failure was a thing of the past, a quaint old concept like 'Great' Britain rather than United Kingdom. However maybe with Scotland angling for independence it should be dis-United Kingdom. No tea and crumpets these days!
