The history of hard drives is probably as old as computers as they were first introduced by IBM in 1956. Ideally, a hard drive is used to store all kinds of information on a system (if it is an internal drive). It is considered as non-volatile storage, which is different from a computer's primary memory (RAM). An internal drive is connected to the system's motherboard as well as a power socket. Nowadays, external hard disks based on flash memory are extensively used as well. Since magnetic hard disks are still the most commonly used variety of drives, we will consider its example to explain how it works. Ideally, it is a cylindrical unit that consists of various magnetic plates. Each plate is divided into numerous tracks and sectors. The plate consists of minute units that are used to store data in a binary form (0 or 1). A spindle is located in the middle of the disk that rotates the unit. Now, whenever we wish to access or store data, a read/write head is moved to a particular area. On the basis of technology: Mostly, hard disks can either be HDD (Hard Drive Disk) or an SSD (Solid State Drive).Ideally, hard disks can be distinguished into different categories on the basis of numerous parameters like these: What are the different types of hard disks? The spindle rotates the drive and the head either reads or writes the data on it. HDDs are based on magnetic disks, have slow processing, and are cheaper. Since they have a read/write head, they produce a sound while operating. On the other hand, SSDs are based on flash memory and does not produce any sound. On the basis of use: Hard disks can also be categorized as internal or external.They are safer, faster, and more expensive. An internal drive is the native storage of the system which is placed inside the unit. An external drive is an extended storage unit that is used to take a backup or transfer data. On the basis of size and format: Needless to say, hard disks can be of different sizes ranging from gigabytes to terabytes and of various disk formats.It can be connected to the system via a USB cable. Since Solid State Drives (SSDs) are newer and more advanced, they are considered better than HDDs. Not only are they faster, but they are also more secure than a magnetic disk.
