from oldest to newest

We do not realize, but the data storage is an integral part of our daily lives. Now, it would be hard to do without it.

From installing Windows 10 on our new SSD hard drive, or transferring a PowerPoint presentation to a USB keystoring your data has become an important and natural action.

What does storage space mean?

First of all, it is necessary to understand what it means storage spaces. This computer term usually corresponds to the various methods and supports we can use. They allow us topermanently save our computer data. Compared to random access memory (RAM)this technology primarily exists to assist the processor of your computer or smartphone in processing data.

We can classify different storage methods into two main categories

– Ang offline storage spaces which includes all “traditional” physical storage media. Those must be entered directly and materially into a system to have access to the recorded data. We can usually mention optical discs such as DVDang USB key or even the Hard disk.

HDD hard drive

– Ang online storage spaces where ” cloudsis a newer way for backing up data. This technology usually consists of depositing your files on an online platform. Hard disk or any other medium is not useful. The concept is able to access it on different devices. Among the most popular storage services, you have iCloud from Apple ang Google Drive by Googlewhere the Microsoft OneDrive . We will have the opportunity to discuss this in more detail in the third part of this article.

We can categorize different storage media into five generationsunique to find ourselves in it historical classification .

The evolution of storage spaces over time: from punched card to floppy disk

Ang first generationcorresponds to that of physical storage media. Historically, the ancestor of the various computer storage media that succeeded each other remains punch card . In 1887, Herman Hollerith invented the mechanographic machine considered dinosaurs by our current computing devices. Using the punched card, this machine was used during the census of the American population at the time. In fact, the use of the card has greatly facilitated the storage and receipt of information on the person in question.

Herman Hollerith’s mechanographic machine and punch card were successful. Which allowed him to establish his company Tabulating Machine Co. in 1896. In 1917, became IBM (International Business Machine Corporation). IBM led the computer market for much of the 20th century. Note that this is before the rise of its competitors such as Seagateat Toshiba.

In the same year of 1887, American engineer Tlobert lanston would use punched tape, an evolution of the punched card to create his monotype printing typesetting machine . This technology consists of storing the text entered by its user and then making it fonts and finally printing the recorded text.

Ang second generationworries that of magnetic storage media. The first method of storage of this generation was the magnetic tape invented by the German Fritz Pleufmer in 1928. The latter changed drastically in the 20th century, and the oldest of us will surely still recognize it. , especially in VHS tapes.

This magnetic tape is the most widely used format. In the 1950s, this medium was used as a storage medium for computers at that time. Today, VHS tapes are still used. Their storage capacity can reach 5 terabytes and their incredible resistance is around 30 years.

This generation was marked by the rise of IBM, which specializes in the design and sale of computers and hard drives. In fact, Reynold Johnson, of this same company, invented first hard drive . IBM designed this computer innovation at the request of the US Air Force and named it the Ramac 305 with a capacity of 5 megabytes for the price of $ 50,000.

Internal hard drives and external HDDs

IBM did not stop inventing the hard disk, because with this generation of magnetic media, they were also the designers of the floppy disk in 1967. This computer storage medium provided the IBM 370 computers. has a size of 3.5 ” for a capacity of 1.44 MB of storage memory and a price of 70 francs in the 80s.

The evolution of storage spaces over time: from optical disk to SSD disk

About third generationmethod of storage, it has to do with optical storage media. In the early 1970s MCA developed the first optical storage medium in the United States: the Laserdisc . But this one was not very successful.

10 years later those companies sony at Phillips sold the first CDwhere compactdisc . They have a storage capacity of 700 MB. Their use is mainly for music recording. Currently, compact discs are on the market at a price from 5 to 10 euros.

In 1988, the influence of the optical disc disappeared after its advent recorded version: ang CD-R. This change allows ordinary people to burn their own discs at home using a computer and a burner drive. Except that this recorded compact disc cannot be rewritten. It wasn’t until 1997 that companies released a rewritable version of these optical discs, the CD-RW.

In 1995, Japanese companies sony, Toshiba, panasonic and the Dutch company Phillipsinvented the DVD . It is characterized by larger storage capacity compared to CD. DVD-17. It can even have up to 17 GB of storage memory. It was only in the late 90s Pioneer released the recorded version of these optical discs, the DVD-RW.

At the beginning of the 21st century, sony at Pioneer worked together to discover the Blu ray disc in 2006. Compared to its predecessors, the latter is distinguished by its excessive storage capacity. It can be from 25 GB to 200 GB of storage memory. Currently, it is used specifically to store very high resolution videos.

About fourth generation storage media and the latest generation of physical storage media, you have flash storage mediaincluding SD cards,USB keybut also SSD hard drives.

Cloud storage space: the outcome of this evolution?

The omnipresence of Internet but also the increasing evolution of its performance over the past few years has made it possible to democratize fifth generationstorage method: online storage.

Online storage began to take shape at the end of the 20th century. However, it was in the 21st century that the cloud began to be accessible to the general public thanks to the development of the Internet and modern technologies.

Online storage or “Cloud” refers to the newest and most versatile storage medium available. In addition, the cloud is an enabling service to store and transfer our data via the Internet. This operation does not require an external device. So we can access our various files on our smartphone or our computer thanks to cloud platforms.

This technology offers a variety of advantages that are unmatched by so-called traditional storage media. First of all, its price is cheaper than the physical method of storage. For good reason, it is logical that you only pay for the size of the storage memory selected. To get an idea, at Apple for example, you have to pay the $ 10 price to add 2 TB of online storage space for your device.

Another advantage that must be identified is its nature cross-platform . In other words, providers likeMicrosoftwith OneDrive offers access to files stored in the cloud via a variety of devices (computers, smartphones, tablets, etc.) without compatibility problems.

However, the security of our cloud data remains one of the biggest controversies about this change. For more information about the security of this online storage medium, read an article that talks about it in more detail: is the cloud secure?
