These devices not only give you the convenience of accessing your data and protecting you from unscrupulous people, but also ensure that your information is not lost when your computer is turned off. Floppy disks
You can use floppy disk to store small amounts of information. According to Mediastoragedevices.com, a widely used floppy disk has a capacity of 1.44 MB. It records data as magnetized points on tracks on its surface. Floppy disks are portable, allowing you to move data from one computer to another. You have to ensure that you don’t store data on floppy disk for long periods because, as the magnetic field weakens, you risk losing your stored
external hard drive data.
You can store large amounts of data on an external hard drive. An external hard drive is a metal platter coated with magnetic oxide that is magnetized to represent data. You can access information about the hard drive by connecting it to the computer via the USB port. It is not only very fast to access files, but it is also more convenient as it has a large data storage capacity for future use.

The CD-RW (Rewritable Compact Disk) allows you to create your own CD through its write-once -read-many feature. CD-ROM/CD-RW offers you a convenient, safe and inexpensive way to store large amounts of data, given the memory of around 800 megabytes.
USB Flash Drives
The convenience of storing and transferring data from a device that is portable and has a large capacity comes with the USB flash drive.
