7 Largest External Hard Drives You Can Buy

External hard drives are an extremely valuable tool for storing large files. They can hold an incredible amount of information and can easily be transported without the risk of breaking or losing that data.

Hard drives have been around for a long time. They were used to store information on computer hard disc drives, floppy discs, and compact discs.

A general rule of thumb has always been that an external hard drive has to be at least as big as your internal hard drive, period; that is, if you have four terabytes on your internal hard drive, then you ought to get at least a 4TB external hard drive if possible.

These portable storage devices are one of the most popular ways to back up your data. They have a bunch of benefits, such as being able to store large amounts of data but also carrying them around in your pocket.

In this article, we look at eight of the largest external hard drives in the world, which are still available to purchase today.
