An important consideration when building a home computer or server is the data transfer rate of the machine's hard drives. If the speed of the drives in the machine is slow, it will severely degrade overall performance, even if the processor and / or RAM represent a stronger category. It is possible to measure this with all operating systems, it is not different with Linux systems. In this description, we test the speed of our HDD in several ways to get a more comprehensive picture of the status of our devices.

In this description, we install a program called lm-sensors, which first detects the temperature sensors available in the computer, and then we can query their current data at any time. Then we will install a program called hddtemp, which will allow us to read the temperature values ​​of the sensors in our hard disks separately. Thus, during the hottest periods, we can regularly monitor the data of our machine so that we can use it optimally.
