What Is A Petabyte

Data storage has always been essential for both brands and individuals. And that hasn't changed. All that has changed over the years is the method of storage. In the past, storing paper files and certificates was a common practice. But today, electronic data storage has taken over.

And that's no wonder. After all, it is easily accessible and immune to physical damage (fire outbreaks and floods). Above all, you can store a large amount of data on your device without worrying about room space. That said, you still need to pay attention to your data storage units.

As a firm, running out of storage space is a no-go, especially in modern times. There are various units of data storage ranging from the byte to the yottabyte. Hence, you need to determine the amount of data that you'll be dealing with. And that in turn will determine the device you're going to need.


For smaller firms, storing data on USB drives, external hard drives, and PC might do the trick. Plus, there are services such as Google Drive that allow you to store data directly on the net. But what if you need something bigger?

Well, back in the 2000s, people were fascinated by just how much data Gigabyte(s) could hold. However, times have changed. Nowadays, even the most common smartphones hold up to 30GB of storage space. And that's not enough even for average users. So it is no surprise that you (as a brand) may be in the market for devices with higher storage capacity.

If so, this article is for you as it introduces a storage unit that's gradually upstaging even terabytes - the Petabyte. If you're coming across that word for the first time, no doubt you're wondering: "what is a Petabyte?" The answer to that lies below

Petabyte - what it is

In simple terms, a Petabyte is that unit of data storage that's higher than the terabyte and lower than the exabyte. Peta, standing for five, consists of approximately 1000⁵ bytes. The Petabyte is the fourth largest data storage unit and has become widely used by large firms.

To further understand it, let's see how it compares with the other units of data storage.
