Top 20 Storage Devices and Accessories Worth Buying Online


A storage device for a computer enables its user to store and safely access the data and applications on a computer device. Knowing and learning about these computer storage devices is necessary as it works as one of the core components of the system.In terms of Computer Awareness as well, the user must be aware of the various elements which together contribute to the working and functioning of any computer device. Thus, in this article, we bring to you the various storage devices of a computer along with their functions and uses.Also, for candidates preparing for competitive exams, some sample computer storage devices questions have been given along with their answers. Aspirants who are preparing for exams which comprise Computer Knowledge as a subject in the syllabus can refer to them for assistance.

Types of Computer Storage

The computer storage unit is divided into three parts. Given below are details about the three types of computer storage:

  • Primary Storage: This is the direct memory which is accessible to the Central Processing Unit (CPU). 
    • This is also known as the main memory and is volatile.
    • This is temporary. As soon as the device turns off or is rebooted, the memory is erased
    • It is smaller in size
    • Primary storage comprises only of Internal memory
    • Examples of primary storage include RAM, cache memory, etc.
  • Secondary Storage: This type of storage does not have direct accessibility to the Central Processing Unit.
    • The input and output channels are used to connect such storage devices to the computer, as they are mainly external
    • It is non-volatile and larger storage capacity in comparison to primary storage
    • This type of storage is permanent until removed by an external factor
    • It comprises of both internal and external memory
    • Examples of secondary storage are USB drives, floppy disks, etc.
  • Tertiary Memory: This type of storage is generally not considered to be important and is generally not a part of personal computers.
    • It involves mounting and unmounting of mass storage data which is removable from a computer device
    • This type of storage holds robotic function.

Characteristics of Computer Storage Devices

Over the years, the usage of computer and electronic devices have massively increased and so has the dependency on them. Personally or professionally a lot of data is entered into the computer and storing it becomes a must for future use. Thus, these internal and external storage devices have come in as a savior for the users.

In case of less memory space in the device, the various computer storage devices can be used to save the data securely without losing it.

Given below are a few characteristics of these storage devices:

  • Because of volatile memory, the data stored can be saved and also replaced whenever needed
  • These devices are readable, writable and rewritable which ensures that the data saved if not necessary can be removed or replaced accordingly
  • Accessibility to these has become very easy and convenient. The devices are easily available online and offline and need no expertise for usage
  • The capacity and size of these drives and devices has become an added advantage
  • Even in terms of performance, using these storage devices the data can be saved easily but can also be transferred easily from one device to another.
    • speed (how quickly data can be accessed)
    • cost per storage unit (i.e. price per gigabyte or megabyte)
    • durability (toughness)
    • portability (how easy it is to move it from one computer to another)

Indeed, the types of storage devices mentioned are not ubiquitous and widely used in the healthcare industry as compared to software programmes such as Patient Archiving Communications System (PACS) and Electronic Health Records (EHR) in securely storing patients’ data and reports as well as physicians’ diagnoses. However, some of these devices may be required in certain situations and increasing our awareness about how these devices work and their uses may enhance the efficiency in the workflow of the situation. Nevertheless, the drawbacks derived from some devices cannot be overlooked. We have to be careful in selecting the types of storage devices we wish to employ for a certain task so that we are not encountered with undesired consequences which may or may not be reversible.
