Information storage media

HalfIn the field of computing, it is essential to store information for later consultation, as well as programs so that they can be executed as many times as desired. Objects that serve this purpose are called storage media and have a wide variety of forms and functionality. They can be classified into:

* magnetic type discs, how are the hard drives and the flexible or floppy;
* Optical Discs, where we find the CD, the DVD, the Blu-ray and the discontinued HD DVD;
* magneto-optical discs, like the popular Zip, Jaz and SuperDisk from Iomega.

Of course the list goes on with magnetic tapes and business cards. memory. The latter are usually associated with the acronym SD, in its variants MicroSD, SDHC, but there are many more, whether standardized such as Compact Flash or made to measure for the products of a particular company, such as those used by the Sony portable console and the long-forgotten Memory Sticks.

In the beginning, media such as CDs did not allow the writing of data to end users, but were used to distribute music, applications and games, with the benefit of having hundreds of times more space than floppy disks. As time went by, the market began to offer blank recorders and CDs, however limited to a single copy. The inevitable evolution of this format brought with it discs capable of being rewritten, which was repeated in the generations that followed: DVD and Blu-ray.

It is curious that a computer use so many different types of storage media, which vary not only in technology but in performance and durability. Hard drives, for example, run the risk of being unusable due to the fact that they consist of mechanical components, also due to the noise level that some models produce. The market trend is to make flash memory the only class, eliminating many problems and offering smaller, faster and more resistant devices.
