Monitoring The Life Span Of Your Hard Drive
Backblaze, an independent company, tracked all the data for 25,000 drives for the next four years to know the actual lifespan of a hard drive. They keep a record of all the drives. When a hard disk fails, they take note of the date and change it will a brand-new replacement. Over the years they were able to come up with graphs and data that summarize the average life of a hard disk. Based on the data they have collected, hard disks fail on three distinct phases. The first phase lasts 1.5 years from the year of purchase has a failure rate of 5.1%. The second phase lasts 3 years from the original phase of purchase and has a failure rate of 1.4%. The last phase which is three years onwards from the original purchase date has a failure of 11.8%.
Failure Percentages ExplainedThis means that on the first phase, the chance that your hard drive will be destroyed is only 5.1%. This is very slim and this means that your hard disk is unlikely to fail after 1.5 years. The second failure rate which is also on the second phase is even reduced to 1.4%. This means that once your hard disk makes it to the second phase, you have a very tiny chance of having a failed hard disk. Your hard disk can last on average for three years without problems.
The Last Phase
In the last phase or beyond three years from the original date of purchase, it has a failure rate of 11.8%. This is a huge leap from the 1.4% that you got in the second phase. This means that your hard disk is likely to fail after the third year and you might need to replace it during this time. If you can’t replace it, better backup your files regularly.
