Perforated cards:
This storage device was used in the 1950s and could store up to 960 b. The perforations of the cards represented the zeros (0) and the non-perforated spaces, the ones (1). Storing a single 2-minute MP3 file would have forced more than 40,000 cards to be used. -
The floppy disk
The floppy disk was a magnetic type data storage medium, it was made with a thin circular sheet of flexible and magnetizable material, enclosed in a plastic cover, square or rectangular, which was used in the computer, for example: for a disk Bootable media, to transfer data and information from one computer to another, were simply to store and protect files. -

3.5 floppy
The physical structure of floppy disks has been modified throughout history, just as their physical density and storage density have changed. Speaking of its inner workings, it was a magnetic disk where the data is stored. In order for the unit to access them, a mechanism removes the metal flap that serves to protect its integrity and rotates it at a speed of 300 revolutions per minute while inspecting its two reading-recording heads -
The Zip disk
The Zip disk was a read and write head mechanism, it was mounted on a linear actuator that flies over a polymer disk, there was a similarity to a floppy disk, it rotates quickly inside a rigid plastic cartridge. The linear actuator uses the moving coil technology, related to modern hard drives. The Zip disk is 9 centimeters in size. -
CD
It was an optical disc used to store data in digital format, there was storage of audio, images, videos, documents and other data, They have a diameter of 12 centimeters, a thickness of 1.2 millimeters, can store up to 80 minutes of audio or 700 MB of data. This technology was initially used for audio CDs, and was later expanded and adapted for data storage, video storage, home recording, and mixed data storage, and I think the album became popular in today's world. . -
DVD
I think the growth of computer technology is impressive since the CD has become too small, since all applications, be they programs, operating systems or video games, take up much more memory. Of the traditional ones. When there was the first DVD sales explosion, the video format appeared, the advantages of DVDs were clear: the more capacity, the better quality can be stored. And the data is better preserved, -
USB
I think USB sticks have become the most widely used personal data storage and transport system, replacing traditional floppy disks and CDs in this use. the existing capacity is 1, 2, 4, 8, 16, 32, 64, 128, 256, 512 GB and up to 1 TB (1000 GB) are available in the market, before this was difficult to store, USB drives of greater capacity, due to its price, being out of the reach of the "internal consumer". -
micro SD
It is a format for flash memory cards. Used only in mobile phone devices, portable GPS devices, MP3 players, video game consoles, and USB flash drives.MP3, video game consoles, these cards were not made for computers or other electronic devices -
Cloud storage
The current storage options are practically unlimited thanks to the storage in the cloud, available from any device with an Internet connection, I think that this storage is one of the most important that has marked the history of humanity since , is a new technological advance,
