In a society where technology has taken over most of our daily activities, it would already be impossible to see someone walking without any gadget on their hand. May it be a phone, a tablet, a smartwatch, etc. It is already a part of our system, and once you pull it out, it would take time to get used to.
Technology also has made a lot of things easier, from house chores to industrial-scale jobs. Machines have worked their way up in the industry, staying on the track of improvement, we can say that it has evolved a lot faster than our ancestors have imagined. Technology has been giving a good solution to almost every problem we have, and so far, it has shown effectiveness and efficiency.
Long before the invention of flash drives and memory cards, they have used hard drives as big as two modern refrigerators which can store 5 million 6 bit characters. That is not even a significant portion of the current 64gb stock memory of your phone. But as I have said, technology has come a long way.
Clouds have been invented to relieve the problem of having physical disc drives that you carry with you all the time. It is a very accessible media, and you can easily access your file from anywhere in the world as long as an internet connection is available.
Look at it as a SATA drive without actually having a physical SATA drive. One has an individual account, provided with the needed security- usernames and passwords- and voila, your data can already be retrieved. Instead of limiting yourself with a couple of gigabytes or GB of storage, clouds can provide you with almost unlimited data storage.
Cloud storage has proven its capabilities in storing and retrieving data. With the use of a stable internet connection and a gadget, you can access anything you have stored beforehand and store anything, anytime and anywhere. It has shown cost efficiency in every way, having to be able to store unlimited data without the bulk of holding a physical hard drive is proof.
You also do not have to worry about losing your data or someone hacking into your account, cloud storages have improved their security through time. Most clouds offer encrypted securities which only the account owner can access. In cases that you forget your access to the cloud, companies have a systematic approach to data recovery and retrieval.
