Data Storage
This article lists the various computer information systems/storage types and how they work. This article includes definitions of various types of storage, from hard drives and flash memory, such as USB drives and solid state drives (memory cards), to optical discs and smart cards. We currently use smart cards more than this article suggests.
Hard Drives
Every computer contains one, if not two, hard drives. There are internal and external hard drives. The internal hard drive is located inside the system unit, and the external hard drive is connected to the computer for extra storage. It is vital that an owner of a computer purchases an external hard drive to backup his or her computer in case it crashed. An external hard drive is extremely convenient to store information; however, one must be cautious of the possibility of "hard drive theft" because it is easy for someone to access a random, external hard drive into their own computer. Many people today use a finger print or password to access to their hard drive because of this reason. Without a hard drive, one could not store the countless amount of information contained to a computer. The hard drive holds a port to connect to the motherboard. There are a wide range of capacity for hard drives, depending on the computer owner's preference. Magnetic hard drives and solid-state hard drives are two common hard drives used for computers. A magnetic hard drive is the term computer users mean when they say hard drive, and solid-state hard drives cause flash memory technology. Without hard drives, many information and data would be lost and forgotten.

Hard drives are used as primary storage units to store most data and computer programs to operate on a computer. The two types of hard drives available for purchase are: internal hard drives, and external hard drives. There are many things to consider if you are a consumer seeking these storage devices. The internal hard drive, which can be included in the computer before purchase, is directly connected to the motherboard, (A.K.A the brain of the computer), as well as other components inside the tower or casing of the computer/laptop. An external hard drive is commonly used among users who are either portably transporting data/programs from device to device, or seeking extra storage space for their files. External hard drives can be very small, and convenient for traveling with data. There are multiple different options to explore while considering a hard drive: speed, consistency, and durability. The types of hard drives offered include either of the following: magnetic storage, optical storage, and electrons which use flash memory media.
