I wanted to know what is the life expectancy in years of WD SATA 500 GB hard drive. Also how do they measure reliability with MTBF
THANKS.

IMO..."life expectancy" and "hard drive" do not belong in the same thought process.  A hard drive may fail at any moment, any time...and a user might buy the same drive and use if for 10 years or so, with no problems.

 

Every hard drive is a crapshoot...that's the reality of using computers.  There is no reliable (IMO) way of asserting such a thing as "expected useful life" for a hard drive.

 

But...I will say that...a brand-new hard drive will have no warranty coverage beyond 3 years and some not even beyond 1 year.  I believe that's a strong message to those users who think that "tomorrow" will be like "today".

Louis, at #2, makes valid points about the chances with any one hard drive. Any and all electronic equipment will eventually fail, and if you add in mechanical components, as in 'spinning rust' hard drives, it only becomes more certain. One brand new HD can fail straight out of the box, the next one to it off the production line can soldier on for ten years.

 

In general, electronic equipments have a relatively high rate of failure when brand new. Typically this falls to very low failure rates across their expected service life and the failure rate then starts climbing again - the bath tub shaped curve.

 

MTBF (Mean Time Between Failures) is calculated in part from the design parameters, from product experience, and from engineers' best guesses. At least it is usually engineers' guesses and not the sales department's !

 

The only defense against the possibility of a hard drive failure is data back ups. Back up your data regularly and religiously.

Hi

I will go one step further, since a Traditional hard drive is a combination of a mechanical and a electronic device I take the viewpoint that if I plan to use it within a short period I leave it on, otherwise if it will be over an hour for example I power down to save the mechanical parts of the entire computer. That would be cooling fans, Power supply fans & hard drives.

That also helps reduce dust build up on the CPU heatsink as well as save energy.

 

Good Luck

Roger
