What is a storage device?
A storage device is a kind of hardware, which is also known as storage, storage medium, digital storage, or storage media that has the ability to store information either temporarily or permanently. Generally, it is used to hold, port, and extract data files. It can be used either internally or externally to a computer system, server or any comparable computing device to hold information.
For any computing device, a storage device is one of the core components that is available in several structures and sizes on the basis of requirements and functionalities. Except for hardware firmware, it stores virtually all the data applications in a computer. A storage device is available in various form factors; for case, a computer device includes different storage media such as hard disk, RAM, cache. They also have optical disk drives and externally connected USB drives. Two types of storage devices, primary and secondary are available there to store data.
Secondary storage devices: The hard disk, USB storage devices and optical disk drive are examples of secondary storage devices, which are designed to store data permanently. They include a large storage capacity while comparing with primary storage devices.
Why is storage needed in a computer?
A computer would be considered a dumb terminal without a storage device. It cannot store or hold any type of information or settings if it has no storage device. Although your computer can run without storage media, you only can view or read the information on it unless it was a computer that is connected to another computer contained storage abilities. Furthermore, a storage device is needed to store information about such tasks, like browsing the Internet.
What is a storage location?
When you store any type of information on a computer or other similar devices, it may ask you to the storage location where you want to store the information. By default, there is various type of data stored on your computer hard disk. If you want to move this information to another device, you need to transfer it to another storage media, like a USB flash drive that makes capable you to move it to any other computer.
Why so many different storage devices?
As the use of a computer is increasing rapidly, the technologies used to store data are also increasing day by day due to the higher need for storage capacity. There is need to invent the new technologies as the use of storage device is increasing day by day and people want take it with them. As new storage devices are invented, people replace the old device with a new storage device. Therefore, the need for older devices is ended and stop being used.
The CD-ROM drives replaced them with the introduction of floppy diskettes, and CD-ROM was replaced by DVD drives. Then flash drives are designed to replace the DVD drives. The cost of the first hard disk drive from IBM that contained only 5 MB was $50,000. In modern times, we have smartphones that contain much storage capacity at a smaller price, which can also be carried out in pocket easily. Furthermore, every enhancement of storage device makes it capable of a computer system to store a large amount of data, including accessing it speedily.
Examples of computer storage
Magnetic storage devices
Nowadays, magnetic storage is commonly founded on hybrid hard drives or extremely large HDDs.
A list is given below of magnetic storage devices:
Optical storage devices
Another type of storage devices are given below:
Flash memory devices
Flash memory is cheaper as well as portable. Due to become more reliable and efficient solution, most magnetic and optical media have replaced by flash memory device.
Online and cloud storage
The need to store data online and in cloud storage is increasing rapidly.
Initially, computers were not able to store data on any storage technologies, like flash memory devices, optical storage devices; they had to depend on paper. In modern times, the method of paper storage to store data is rarely used or found.
Which storage devices are used today?
Although there are various storage devices, most of the storage devices have explained above are not in use today. In modern times, most computers mainly use SSD to hold data, including flash drives and cloud storage. Some of the laptops and most desktop computers use a disk drive, which has the ability to read and write CDs and DVDs.
Are storage devices input and output devices?
Storage devices are not considered as input and output devices; however, they have the ability to forward and receive information in the form of storing data, these devices are not input or output devices. It will be more suitable to consider these devices as a storage device rather than input or output devices as they are capable of reading and storing data.
What is the latest storage device?
The NVMe, stands for Non-Volatile Memory Express, is one of the most recent storage device technologies. The cloud storage and SSDs are also becoming recently developed storage devices. Also, some older storage device technologies such as tape drives and hard disk drives are also introducing new technologies for holding much data.
How do you access storage devices?
To access a storage device on the computer or laptop, it is dependent on the operating system, which is being used in the system. For instance, if you are using Microsoft Windows, you can use Windows Explorer on computer that is its default file manager. To open Windows Explorer, you need to double click on the My Computer shown on the desktop screen, or you can use a shortcut key Window key + E. Additionally, Finder is considered the default file manager on the Apple computers.
What storage device has the largest capacity?
The SSD or hard disk is the largest storage device for most computers. Also, computers that have network connections may have the ability to access larger storage with cloud computing, NAS devices, or cloud computing.
Although there are several storage devices available with different capacities, for example, when the hard drive was developed, it had only 5 MB capacity. But now, it can store data up to several terabytes in size. Because with the development of the hard disk, its storage capacity has been increased.
