A Google research study revealed something about the hard disk temperature. While a lot of PC users are trying to keep their hard disk as cool as possible, the study showed exactly the opposite. The rate of hard disk failure increases especially in low temperature, below 30c. Only disks which are older than 3 years behave as expected. However, failure rate only increased when temperature went to about 45c and above. So meaning to say, hard disk cooling systems for home user like us, are basically unnecessary. Research also showed that pleasant temperature should be around 40c.
This is one of the most extensive tests in the IT industry. Google collected and analysed about 100,000 hard disks, included PATA and SATA models capacity range from 80GB to 400GB which majority of home users purchase, from its own data processing centre over the period of nine months.
So now we all know how to take good care of our hard disks.
