HDD

A Hard Disk Drive (HDD) is a classic data storage device that utilizes spinning disks, or platters, coated with a magnetic material to store and retrieve data. An actuator arm with read/write heads accesses data by moving over the spinning platters. HDDs offer large storage capacities at a comparatively lower cost per gigabyte, making them suitable for applications where massive data storage is required, such as servers and desktop computers. However, HDDs are slower in terms of read and write speeds compared to SSDs due to the mechanical nature of their operation. They are more susceptible to physical shocks and are less energy-efficient due to the need to constantly spin the platters.
