Now we have the answer to our question ‘how long does a hard drive last’, let’s dig in and see what this means in a practical sense.
Why do hard drives fail so often?
The high initial failure rate can be chalked up to manufacturing defects. Every batch of hard drives will have a few lemons. After that, the failure rate levels out to 1\% per year. This is explained by random drive failures. Then after three years, hard drives begin to wear out.
