What is Storage Function ?

  • Storage is the activity of storing products at warehouses and logistics centers. Its role is to provide a steady supply of goods to the market to fill the temporal gap between producers and consumers. It also plays an important role in maintaining quality at warehouses and logistics centers and value of products.

  • The storage function measures the amount of energy that is stored inside the system at any instant of time. It is reasonable to expect that the value of the storage function at a particular time instant depends only on the past of the time trajectories through the memory of the system.



Storage Device :-

  • A storage device is a piece of computer hardware used for saving, carrying, and pulling out data. It can keep and retain information short-term or long-term.

  • Storage device is any hardware capable of holding information either temporarily or permanently.

  • It can be a device inside or outside a computer or server. Other terms for the storage device are storage medium or storage media.

  • A storage device is one of the basic elements of any computer device.

  • It almost saves all data and applications in a computer except for hardware firmware.

  • It comes in different shapes and sizes depending on the needs and functionalities.



Types of Storage Devices -

There are two different types of storage devices:

BASIS Primary Storage Device Secondary Storage Device
Size Smaller Larger
Data Retention Temporary Permanent
Location Internal Internal / External
Examples RAM, Cache Memory Hard disk, Compact Disk Drive, USB storage device



Examples of computer storage :-

Today, there are three types of media used to store computer data: magnetic storage, optical storage, and solid-state storage.


Magnetic storage devices -

Today, magnetic storage is one of the most common types of storage used with computers. This technology is found mostly on extremely large HDDs or hybrid hard drives.

  • Floppy diskette
  • Hard drive
  • Magnetic strip
  • SuperDisk
  • Tape cassette
  • Zip diskette
  • Compact Disc or CD


Optical storage devices -

Another common type of storage is optical storage, which uses lasers and lights as its method of reading and writing data.

  • Blu-ray disc
  • CD-ROM disc
  • CD-R and CD-RW disc.
  • DVD-R, DVD+R, DVD-RW, and DVD+RW disc.
  • Solid-state storage devices
  • 128 GB SanDisk Ultra Flair USB Flash Drive


Solid-state storage devices -

Solid-state storage (flash memory) has replaced most magnetic and optical media as it becomes cheaper because it's the more efficient and reliable solution.

  • USB flash drive, jump drive, or thumb drive.
  • CF (CompactFlash)
  • M.2
  • Memory card
  • MMC
  • NVMe
  • SDHC Card
  • SmartMedia Card



Why is storage needed in a computer?

  • Without a storage device, a computer cannot save or remember any settings or information and would be considered a dumb terminal.

  • Although a computer can run with no storage device, it would only be able to view information, unless it was connected to another computer that had storage capabilities. Even a task, such as browsing the Internet, requires information to be stored on your computer.



Which storage devices are used today?

  • Most of the storage devices mentioned above are no longer used with today's computers. Most computers today primarily use an SSD to store information, and the ability to use USB flash drives and access to cloud storage. Most desktop computers and some laptops include a disc drive that is capable of reading and writing CDs and DVDs.



What storage device has the largest capacity?

  • For most computers, the largest storage device is the hard drive or SSD. However, networked computers may also have access to larger storage with large tape drives, cloud computing, or NAS devices. Below is a list of storage devices from the smallest capacity to the largest capacity.
