"This is a joke, right? Do you even know how MTBF is calculated?
Do some reading chucklehead."
Actually, I did and I still believe that the MBTF value in non-serviceable computer components is utter BS.
I wasn't saying MTBF is BS. I was saying that its use as a marketing term is.
There are several MTBF calculations floating around, let's start with the admittedly dubious one on WikiPedia:
MTBF is defined as "SUM(downtimes - uptimes)/failure-count" of a system.
Where a 'downtime' is the exact time of failure and the 'uptime' is the the exact time of the repair.
Wiki: "The MTBF is typically part of a model that assumes the failed system is immediately repaired (zero elapsed time), as a part of a renewal process."
Now consider that Hard disk drives are NOT USER SERVICABLE and therefore cannot be repaired. This would make the MTBF figure BS as the uptime can never occur. So your calculation would be (X-∞)/1 = -∞ Insert your own value for X.
So in actual fact, by this calculation - any device which cannot be repaired has a MTBF of minus infinity.
Granted this is a huge oversimplification.
There are other calculations floating around, such as 1/sum(MBTF of all components) which actually start approaching some semblance of sanity... but you know what? I can't be bothered to type them out and critique them for being used in this context.
MTBF has relevance in some fields, but they have no business being used as a marketing term on a non serviceable device - they should be using MTTF instead, and going on personal experience with WD - that would be <2 years
Chucklehead indeed. Try putting forward an actual argument. Prat.
