Hard drive

The hard drive is the storage place for data from the computer, unlike RAM which is a volatile memory used only to transmit information in the operation of the computer. The most important feature of the hard disk drive is capacity (usually expressed in gigabytes or GB) because it determines the total amount of data that can be stored. However, you should pay special attention to its performance as well, particularly its rotational speed. If this speed is too low, it can penalize the overall capabilities of the system.
