Home Computer Storage Devices
Storage devices are divided into two types 1) Primary Memory 2) Secondary Memory
- Primary memory (main memory): These types of memories are volatile memory. i.e. if the computer turn of the all the data & information written on RAM will be erased automatically.
- RAM (Random Access Memory/Read-Write Memory) : It is a volatile memory after switch off the computer, every thing erase written in it.
- Static RAM (SRAM) : Data store in it never change until we change it or power off the computer.
- Dynamic RAM (DRAM) : Data store in it change or refresh after a specific time.
- ROM (Read-only-memory)
- PROM : PROGRAMABLE ROM
- EPROM : ERASABHLE PROGRAMABLE ROM
- EEPROM : ELECTRICALLY ERASABHLE PROGRAMABLE ROM
- RAM (Random Access Memory/Read-Write Memory) : It is a volatile memory after switch off the computer, every thing erase written in it.
- Secondary memory (storage devices) : : These types of memories are non-volatile memory. i.e. if the computer turn of the all the data & information written on RAM will remain unchanged.

The external hard drive is undoubtedly the best and safest computer backup device as it offers extensive storage space and incorporates several safety features as well. In addition to this, it is physically strong and well guarded which keeps it from sustaining any physical damages, unlike CDs and DVDs. Part 2: Top 5 Best Computer Backup Drives.

- Computer Storage Inevitable to modern computing, storage systems are used in all computing platforms - from large super computers to hand-sized devices, all store data permanently or temporarily. The first data storage was a punch card that that kept a few bytes; storage systems now topple multi-Terabyte capacities with comparatively less power.
- Storage Devices. Storage devices are divided into two types 1) Primary Memory 2) Secondary Memory. Primary memory (main memory): These types of memories are volatile memory. If the computer turn of the all the data & information written on RAM will be erased automatically. RAM (Random Access Memory/Read-Write Memory): It is a volatile memory after switch off the computer, every thing.
Alternatively referred to as digital storage, storage, storage media, or storage medium, a storage device is any hardware capable of holding information either temporarily or permanently. The picture shows an example of a Drobo, an external secondary storage device.
There are two types of storage devices used with computers: a primary storage device, such as RAM, and a secondary storage device, such as a hard drive. Secondary storage can be removable, internal, or external.
Examples of computer storage
Magnetic storage devices
Today, magnetic storage is one of the most common types of storage used with computers. The mule torrent yify. This technology is found mostly on extremely large HDDs or hybrid hard drives.

Optical storage devices
Another common type of storage is optical storage, which uses lasers and lights as its method of reading and writing data.
Flash memory devices
Flash memory has replaced most magnetic and optical media as it becomes cheaper because it is the more efficient and reliable solution.
Online and cloud
Storing data online and in cloud storage is becoming popular as people need to access their data from more than one device.
Paper storage
Early computers had no method of using any of the technologies above for storing information and had to rely on paper. Today, these forms of storage are rarely used or found. In the picture is an example of a woman entering data to a punch card using a punch card machine.

A hard copy is considered a form of paper storage, although it cannot be easily used to input data back into a computer without the aid of OCR. Imovie for high sierra.
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.
Why so many different storage devices?
As computers advance, the technologies used to store data do too, with higher requirements for storage space. Because people need more and more space, want it faster, cheaper, and want to take it with them, new technologies have to be invented. When new storage devices are designed, as people upgrade to those new devices, the older devices are no longer needed and stop being used.
For example, when punch cards were first used in early computers, the magnetic media used for floppy disks was not available. After floppy diskettes were released, they were replaced by CD-ROM drives, which were replaced by DVD drives, which were replaced by flash drives. The first hard disk drive from IBM cost $50,000, was only 5 MB, big, and cumbersome. Today, we have smartphones that have hundreds of times the capacity at a much smaller price that we can carry in our pocket.
Each advancement of storage devices gives a computer the ability to store more data, and save and access data faster.
What is a storage location?
When saving anything on a computer, it may ask for a storage location, which is the location information is saved. By default, most information is saved to your computer hard drive. If you want to move the information to another computer, save it to a removable storage device, such as a USB flash drive.
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.

Many storage devices have been available in many different capacities. For example, over the evolution of the hard drive, their storage capacity has increased from 5 MB to several terabytes in size. Therefore, the list below is only meant to provide a general idea of the size difference between each storage device, from smallest to largest storage capacity. There are exceptions to the list.
- Hard drive / SSD
- NAS / Cloud Storage
Are storage devices input and output devices?
No. Although these devices do send and receive information, they are not considered an input device or output device. It is more proper to refer to any device capable of storing and reading information as a storage device, disk, disc, drive, or media.
How do you access storage devices?
Accessing a storage device on your computer depends on the operating system your computer uses and how it's being used. For example, with Microsoft Windows, you can use a file manager to access the files on any storage device. Microsoft Windows uses Explorer as its default file manager. With Apple computers, Finder is considered the default file manager.
What is the latest storage device?
One of the most recent storage device technologies to be introduced is NVMe, with SSDs and cloud storage also being recently developed storage devices. Also, older technologies, like hard disk drives and tape drives, are always developing new techniques to allow for the devices to store more data.
