storage device types
BASIC STORAGE DEVICE TYPES:
- THE 8 MAIN AND BASIC STORAGE DEVICES WHICH WE USE IN OUR DAILY LIFE:
Floppy Disk.
Tape.
Compact Disc (CD)
DVD and Blu-ray Discs.
USB Flash Drive.
Secure Digital Card (SD Card)
Solid State Drive (SSD)
HARD DISK DRIVE:
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that uses magnetic storage to store and retrieve digital data using one or more rigid rapidly rotating platters coated with magnetic material.
FLOPPY DISK:
A floppy disk is a magnetic storage medium for computer systems. The floppy disk is composed of a thin, flexible magnetic disk sealed in a square plastic carrier. ... When hard drives were still very expensive, floppy disks were also used to store the operating system of a computer
TAPE:
A tape is a magnetically thin coated piece of plastic wrapped around wheels capable of storing data. ... Today, tape has mostly been abandoned for faster and more reliable solutions like disc drives, hard drives, and flash drives that are all direct access and cloud storage.
COMPACT DISK(CD)
A Compact Disc, also called a CD are small plastic discs which store and retrieve computer data or music using light. Compact Discs replaced floppy disks because they were faster and could hold more information. The CDs made floppy disks become obsolete. ... The diameter of a normal CD is 120 mm.
BLUE RAY AND DVD
Blu-ray Disc (BD), often known simply as Blu-ray, is a digital optical disc data storage format. It was designed to supersede the DVD format, and is capable of storing several hours of video in high-definition (HDTV 720p and 1080p). The main application of Blu-ray is as a medium for video material such as feature films and for the physical distribution of video games.
USB FLASH DRIVE:
USB flash drives are often used for storage, data back-up and transfer of computer files. Compared with floppy disks or CDs, they are smaller, faster, have significantly more capacity, and are more durable due to a lack of moving parts.
SD CARD:
A Secure Digital (SD) card is a tiny flash memory card designed for high-capacity memory and various portable devices, such as car navigation systems, cellular phones, e-books, PDAs, smartphones, digital cameras, music players, digital video camcorders and personal computers.
SSD:
SSD. Stands for "Solid State Drive." An SSD is a type of mass storage device similar to a hard disk drive (HDD). It supports reading and writing data and maintains stored data in a permanent state even without power. Internal SSDs connect to a computer like a hard drive, using standard IDE or SATA connections.
