Storage devices are an important component of a computing system, facilitating the storage, porting, and extraction of data files. These memory storage devices can store data, information, files, and so on both temporarily and permanently, as per the user’s requirements.   

What is a Storage Device?

A storage device is essentially a hardware unit in a computing system where information, files, objects, and data are stored. These devices are used for porting, extracting, and storing data temporarily or permanently. Data storage units can be internal to a computing device or added externally, as per your needs. 

There are different types of storage devices with varied structures and sizes, differentiated based on their functionality and underlying device type. The data storage devices can store all the data and applications in a computing device, besides the hardware firmware.

Types of Computer Storage Devices

Data storage devices can be of different types, as per their functionality, structure, device type, size, and so on. Given below is a list of storage devices of computers, that are primary, secondary, and tertiary storage: 

  1. Primary Storage Devices: A primary storage device, also known as internal memory, is a computer storage device that is designed to hold data temporarily. These storage devices are directly accessible to the Central Processing Unit (CPU) and have a fast data access speed. Primary storage devices are volatile and smaller in size, mostly used to store program instructions, input data, and intermediate results. Some examples of primary storage include random access memory (RAM), read-only memory (ROM), cache memory, etc. 
  2. Secondary Storage Devices: Secondary storage devices are mostly external data storage units with no accessibility to the central processing unit. These devices are designed to store data permanently until the memory storage device is removed from the computing system. Secondary storage devices are non-volatile with a larger storage capacity, used for long-term storage of data and programs. USB, floppy disks, optical disk drives, and so on, are examples of secondary storage devices. 
  3. Tertiary Storage Devices: Tertiary storage devices are external storage units that are used for mounting and unmounting mass storage data. These devices are used to store robotic functions, and hence, rarely used in personal computing systems. Tertiary storage devices function automatically, without the need for human intervention. 

List of Computer Storage Devices  

Within the different types of storage devices, there is a list of storage devices, bifurcated based on their specifications, storage capacity, and use. Primary storage, magnetic storage, optical storage, flash memory storage, and cloud storage are some of the computer storage devices: 

  • Primary Storage Devices: Primary storage devices are internal storage units with volatile memory, used for temporary data storage. There are mainly two types of primary storage devices, Random Access Memory (RAM) and Read Only Memory (ROM): 
  • Random Access Memory (RAM): Random access memory is a memory storage device with temporary memory that stores information and data for immediate use. RAM comes installed on a hard disk in the computing device and runs multiple tasks like application loading, web browsing, document editing, and so on.

    The data on RAM gets deleted by shutting down the computing device. On average, RAM storage capacity ranges between 1GB to 32GB, depending on the requirement of the device. There are several types of RAM devices, including Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), and Synchronous Dynamic Random Access Memory (SDRAM). 

  • Read-Only Memory (ROM): Read-only memory is a non-volatile memory storage device where the stored data cannot be edited or modified. The data in this memory storage device is saved permanently at the time of manufacturing.

    ROM is used to store instructions related to starting the computing device, also referred to as bootstrap operation. The storage capacity of these devices ranges between 4MB to 8MB. There are mainly two types of ROM devices, which are Programmable Read-Only Memory (PROM) and Erasable Programmable Read-Only Memory (EPROM). 

  • Magnetic Storage Devices: Magnetic storage devices are external storage devices that can store large quantities of data and information through magnetized mediums. Upon installation, a magnetic field is created between the device and the computing system, allowing the computer to read binary language and store information. Some of the commonly used magnetic storage devices include floppy disks, hard drives, and magnetic strips: 
    • Floppy Disk: It is a removable memory storage device comprised of magnetic elements for storing information and data. 
    • Hard Drive: Hard drives are attached to the motherboard’s disk controller and used to install new programs and applications in a computing system.  
    • Magnetic Strip/Card: Magnetic strips and magnetic cards contain digital data in the form of iron-based magnetic particles. Magnetic strips include debit cards, credit cards, identity cards, etc.  
    • Tape Cassette: Tapes and music cassettes are also examples of magnetic storage devices, storing data in an analog magnetic tape.  
  • Flash Memory Devices: Flash memory devices are essentially portable storage devices used to store and transfer data efficiently. Pen drives, SSD devices, SD cards, memory cards, and multimedia cards are some of the commonly used examples of flash memory devices: 
    • Pen Drive: A USB flash drive stores flash memory integrated with a USB interface. These devices can be connected to any computing device to read/write data and information. 
    • Solid State Drive (SSD): SSDs are mass-storage devices that store data using non-volatile storage. 
    • Secure Digital (SD) Card: SD Cards are portable storage devices used in devices like phones, digital cameras, and so on, for storing large data.  
    • Memory Card: Similar to SD cards, memory cards are used in digital cameras, printers, game consoles, and so on, to store large amounts of data. 
    • Multimedia Card: MMC cards are external storage devices used in radios, digital cameras, etc, to store media files and information.  
  • Optical Storage Devices: Optical storage devices are secondary storage devices that use lasers and lights to detect and store data. Optical storage includes CDs, DVDs, Blu-ray Disc, and so on: 
    • Compact Disc (CD): CDs are optical storage devices that contain tracks and sectors on their surface to store data. 
    • Digital Versatile Disc (DVS): DVSs are similar to CDs, with a higher storage capacity. 
    • Blu-ray Disc: Blu-ray discs are another example of optical storage devices that run on a Blu-ray disc reader. These devices contain violet lasers to store information in greater density and longer wavelengths. 
  • Cloud and Virtual Storage: Virtual or cloud storage is also a part of secondary memory, where storage is hosted on third-party servers and accessible over the internet on a pay-as-you-go basis. Here, the data and information are stored on the cloud, and the underlying infrastructure is maintained by the cloud service provider at physical data centers.
