"The temperature of the hard disk drive is something that you should keep a good eye on in your systems. There are two failure modes for the hard disk drive, which are related to the temperature of the drive itself. In a system, in operation, the hard disk drive heats up, and it needs to be somehow cooled. It does not overheat like other components, such as CPUs [central processing units]."
"And there are two limits. One is the functional limit. So, if a hard disk drive heats up to an internal temperature of 60°C or 70°C, it is still functioning. Above this, it may not function anymore. So internal temperatures of 60°C for server hard disk drives or 70°C for client hard disk drives should be avoided by all means because this is the functional limit."
"Also important, but not so well recognised, is the reliability limit. And there it starts way earlier. Talking about reliability, the annualised average failure rate of a server hard disk drive is 0.4%. That means four out of a thousand per year may fail. This is very low. So, hard disk drives rarely fail. For a client machine, it's a little bit higher. It's 0.9%, which is still less than 1%."
Hard disk drive operating temperature directly affects both functionality and reliability. Airflow is required during operation; drives do not need heat sinks like CPUs but must be cooled. Two temperature-related failure modes exist: a functional limit (internal temperatures around 60°C for server drives and 70°C for client drives can cause loss of function) and an earlier reliability limit where failure rates rise. Typical annualised average failure rates are about 0.4% for server drives and 0.9% for client drives at normal conditions. Monitor SMART temperature-related attributes and maintain optimal average temperatures to minimize multiplied failure risks.
