The Evolution Of Storage Devices
Our minds though powerful, cannot remember every piece of information we take. So storage devices are created to store information. We have come so far, from writing information on paper to physical devices to now via online. Let us see how technology evolved to what we have now, cloud storage.
People use the first method to store data by writing them on paper. However, it is inefficient because writing lots of information would take time. Papers are also easily damaged and lost.
In1956, the IBM 350 was created. This storage device has a capacity of 3.75 MB. It is also big, measuring 60 inches high. This did not last long because of its low capacity with a very high price reaching 3200 dollars.
In the year 1971, the very first floppy disk was created. It was called the IBM 23FD. It is 8 inches in size and can cater to 80 KB worth of data. In the year 1986, a new smaller and better version was created. It was 3.5 inches in size and had a capacity of 1.44 MB. There were many evolutions of the floppy disk. However, the capacity is still not enough.
We finally reached the digital era. In 1982 the first compact disk was created and made available to the market. It had a capacity of 680 MB to 700 MB, a huge leap from the floppy disk. The compact disk is more commonly known as CDs. The data is written on the CD with a laser and is read using CD players. However, you can only store audio and program files on CDs. You cannot change or erase data once you burn the CD.
After the compact disk, the digital versatile disk or DVD was created in 1995. It can cater to 4.7 GB up to 17.08 GB. The way you input data is similar to the CD, but it has more features. Aside from audio and program files, you can now include videos.
The beginning of flash storage. The flash drive was created on 1987. Flashdrives have USBs as ports. Flashdrives are smaller, have a bigger capacity, and best of all, they can be removable. Unlike CDs and DVDs, you can edit the information you put. You can add, erase or change whatever information you have in the flash drive.
After the flash drive came the secure digital (SD) cards in 1999. SD cards can read and write larger data in different electronics. It can be in cameras, game consoles, and, most popular of all, smartphones.
In 2005, micro SD cards were created. They are usually used in smartphones and tablets. And like SD cards, they are used for expandable storage. The only difference is its size and versatility. Micro SD cards are more versatile compared to SD cards. You can put a Micro SD card in any SD card slot as long as you have an adapter.
UFS or universal flash storage is like the HDD and SSD of phones. UFS is created to replace micro SD. They are about the same in size, but they are much faster. Micro SDs can write at less than 100 MBS, while UFS can reach up to 530 MBS. They also make your device quicker in loading apps and web pages.
An HDD or hard disk drive is a storage device used in laptops and computers. They use spinning platters to read and write data. HDDs can read and write data at 30 to 150 MBS.
SSD or solid-state drive is like a better version of HDD. Unlike the HDD, it does not have a spinning platter, so it is quieter and generates less heat. SDD can perform the same actions as HDD but at the speed of 500 MBS.
We have finally reached the latest storage, online storage. Cloud storage allows you to store, share and receive data online. Cloud storage is made for easier access to data. As long as you have an internet connection, you are good to go.
