When storing and moving files or data before the coming of the Universal Serial Bus (USB) drive, it was done first on floppy disks. If the data to be stored was large, it was necessary to have plenty of floppy disks to do it. Some were moving data or files through email but storage too in emails was quite small then. It was quite a task for both floppy and email.
Next were the CD and DVD disks that were able to store larger files or data. Operating system installers were contained only in one CD instead of installers in several floppy disks. Still CDs and DVDs did not have more than 5 gigabytes of storage space. With the arrival of the USB geeks, storage capacity is currently as big as 128 gigabytes!
Fancy USB flash drives
At first, USBs that came along were ordinary rectangular casings called sticks. Not for long manufacturers came up with ideas making them fancy. Some were imbedded in cartoon character figures and other shapes that were nice to have than the standard USB sticks. The sticks followed suit by having colorful prints on them.
Custom flash drives came about when ad people thought of using them as giveaways or promotional items. Many ideas came up on shape and some even came in smaller than the standard 2-inch sticks. Some were only about an inch long only.
Uses of USB
The popularity of the USB made device manufacturers have USB ports on their devices that could be used. Instead of just being used for data and file storage, the USBs are stored with movies and songs that can be played on television and music players. The flash drive can store a big volume of video, photos and music in the latest formats developed to compress those files.
