The internal temperature of a hard drive is an essential factor not only in its correct functioning but also when it comes to the reliability and lifetime of a storage system. The mechanical components of the hard disk drive, especially the fluid-dynamic bearing of the platter-stack spindle, wear out faster at higher temperatures as the liquid oil leaks out at a faster rate. So, controlling the temperature of hard drives in storage systems is necessary to ensure optimal functionality and high reliability. The document explains the following aspects that need to be taken into consideration when talking about the control of the temperature of HDDs:
- Importance of HDD temperature control
- Measuring the hard drive temperature
- Temperature and Reliability

"For correct functioning and the highest possible reliability, it is important to observe the temperature of the hard disk drive in operation. Maximum temperatures of 60 °C and more should be avoided by all means, and the average temperature shouldn't exceed 40 °C."
