Digital Data Storage
Digital data storage is basically the recording of digital information in a storage medium, usually by electronic means. Storage devices typically allow users to store large amounts of data in a relatively small physical space, and make it easy to share that information with others. The device may be capable of storing data either temporarily or permanently.
Digital data storage devices have many uses. For example, computers usually rely on information stores to function. Storage media can also be used to back up important information (storing digital data can involve robustness and reliability issues, so making independent copies of information is usually a wise precaution). Some storage devices are also portable, meaning they can be used to transfer information from one computer to another.
Digital data storage media generally fall into one of five categories: magnetic storage devices, optical storage devices, flash memory devices, online / cloud storage, and paper storage. I’ll provide one or more examples from each category below.
Data Storage Media
Data storage media is a data storage device that functions as a tool / media for storing data and programs where the stored data / program can be read and reopened to be processed again at computeror laptop.
Computer Storage Media has various kinds of media, but in a computer the computer storage device only has 3 categories of data storage media, namely as follows:
- Magnetic Storage Media
- Optical Storage Media (Optical Disk)
- Cloud Storage Media (Cloud Storage)
Magnetic Data Storage Media
Magnetic storage is one of the most common types of data storage used on computers and is the technology used in most computer storage media.
Examples of magnetic storage devices are as follows;
a. Floppy Diskette or Floppy Disk
Floppy Disk Drive or FD is a computer disk drive that allows users to store data on it. Floppy disk is a secondary storage media that can be detached (dislodged). The first floppy disk used was the 5 1/4 “floppy disk, which was later replaced by the 3 1/2” floppy disk.
A 5 ¼ diskette can store 360 KB to 1.2 MB of data, while a 3 1/2 floppy disk can store 360 KB to 1.44 MB of data.
b. Hard Drive or Hard Disk
Hard disk drive (abbreviated Hard Drive, HD, or HDD) is a medium for storing non-volatile data. This means that the data stored on the hard disk will not be lost even if the computer you are using is turned off.
Hard disk consists of one or more plates containing data using magnetic heads. This device is stored in a casing that is connected to the motherboard using an ATA, SCS, or SATA cable, and is also supported by a connection to a Power Supply (power supply).
c. SuperDisk
SuperDisk is a disk drive and floppy disk introduced by 3M, (a company engaged in the office, communications and security). The original SuperDisk was capable of storing 120 MB of data and currently SuperDisks is capable of storing around 240 MB of data.
d. Zip floppy
Zip drives and Zip disks are data storage media developed by Iomega that function the same as standard 1.44 “disk drives and floppy disks.
What makes the Iomega Zip drive unique is its ability to store up to 100MB or even 250MB of data.
This zip disk was very popular in the 90’s, but quickly lost its popularity because users needed more storage media. Hence the CD-R and CD-RW replacing the ZIP disk.
Optical Storage Media
Another type of storage medium is optical storage, these devices use lasers and lights as a method for reading and writing data.
Examples of optical storage media are;
a. Blu-Ray Disc
Blu-ray Disc or BD is an optical disc format developed by thirteen consumer electronics and computer companies. These companies include Dell, Hitachi, Hewlett Packard, LG, Mitsubishi, Panasonic, Sony and TDK.
Blu-ray was first introduced at CES on January 4, 2006. CES stands for Consumer Electronic Show which is a worldwide convention.
Blu-ray discs are capable of storing 25 GB to 50 GB of data. Blu-ray discs are the same physical size as standard CDs.
b. CD-ROM disc
CD-ROM stands for Compact Disc-Read Only Memory is an optical disc that contains audio data. while the CD-ROM Drive or optical drive is the device used to read it.
CD-ROM drives range in speed from 1x to 72x. This means that a 72x CD can be read approximately 72 times faster than the 1x version.
c. CD-R and CD-RW
CD-R stands for CD-Recordable and is writable discs and drives capable of providing information that is written on the disc once and then the disc is read many times after that. Data that is on a CD-R cannot be erased and a CD-R disc cannot be formatted.
d. DVD-R
DVD-R reads DVD dash R stands for Digital Versatile Disc-Recordable, this data storage medium is capable of recording data only once and then the data becomes permanent on the disc. The disc cannot be recorded a second time.
e. DVD + R
DVD + R reads DVD plus R. DVD + R can store 4.7GB of data, while dual-layer discs can hold up to 8.5GB of power.
Flash Storage Media
Recently, Flash memory has started to replace magnetic storage media because flash has a lower price.
Examples of flash storage media are;
a. USB flash drive or Flash Disk
In 1999, Amir Ban, Dov Moran and Oron Ogdan invented the latest data storage system, USB Flash Drive or what we usually call Flashdisk.
Unlike memory cards which are often used in portable electronic media, this media is usually used to move data from one computer to another or to store computer data as backups.
The development of this USB has undergone rapid changes. From its former capacity of only a few Megabytes, nowadays USB Flash Drive media can store up to 16 GB.
Flash disk is a portable data storage medium. The flash disk is about the size of a human thumb and connects to a computer via a USB port.
Flash disks are the easiest devices for storing and transferring information. Flash disks are available in sizes ranging from 2 GB to 1 TB.
Unlike standard hard drives, flash drives have no movable parts; The flash disk contains only the integrated circuit memory chip that is used to store data. Flash drives usually have a plastic or aluminum casing around the memory chip and a USB connector for use in most modern computers.
b. Memory card
Memory Cards were first issued around the 1990s. Memory Card has undergone a considerable evolution also in terms of size and storage data. This media is usually used in practical or portable electronic devices or devices such as cell phones or cameras. This memory development also spearheaded the release of the Flashdisk.
A memory card is a type of storage media that is often used to store photos, videos, or other data on electronic devices. Devices that commonly use memory cards are digital cameras, digital camcorders, laptops, MP3 players, PDAs, cell phones, game consoles, and printers.
There are actually a lot of memory cards on the market, and each of them varies in size, compatibility, and storage capacity. However, I will discuss a more complete discussion of memory cards in another article.
c. Memory Stick
The Sony Memory Stick was first introduced by Sony in October 1998 and is a flash memory card used in Sony digital cameras and other Sony products. Sony releases several Memory Stick models, including Memory Stick PRO, Memory Stick Duo, Memory Stick PRO Duo, Memory Stick Micro (M2), and Memory Stick PRO-HG.
Memory Stick capacities range from 4 MB to 256 GB, with a theoretical maximum capacity of 2 TB. However, until now the 2 TB capacity has not been produced.
d. SSD
The name SSD (Solid State Drive) may have started to be heard in our ears, especially since the presence of the increasingly popular Ultrabook platform has helped boost the popularity of SSD as a storage medium. SSD itself is a non-volatile memory-based flash chip-based storage media.
Non Volatile Memory allows data stored on the SSD not to be lost even if the power is cut off. Meanwhile, Violatile types will lose data when the power is cut off, such as RAM memory (Random Access Memory).
In contrast to Hard Drives, SSDs have no moving parts, which provides advantages such as faster access to stored data and information, no noise, higher reliability and lower power consumption.
Along with its development, SSDs are able to replace standard hard disks on PC and laptop computers. SSDs can also be used for netbooks and other applications that don’t require a lot of storage.
Online Data Storage Media
Nowadays, it is also known as online data storage media. This type of data storage media has begun to be looked at by both individuals and corporations.
-
Google Drive
Google Drive is a facility provided by Google for users who have opened a Gmail account. This convenience is one of Google’s mainstays compared to similar companies.
Users can upload data to their respective Drive and save it. Even with Drive, users can exchange data with each other.
-
Cloud
It’s similar to Google Drive, but the cloud has (of course) different terms and conditions. Cloud Storage is an online storage medium, which can store data on an available virtual server.
With Cloud Storage, you no longer need to store your data on hard drives, CDs, or other hardware. But to be able to use it you need an internet connection.
-
Hosting
Hosting is also an online-based data storage medium. For the majority of using hosting, one must register and pay, unlike Google Drive or Microsoft Cloud.
Thus the article about data storage media of various times and types. Hope this is useful for you.
