Rather than trusting everything to cloud services, it’s always a good idea to have a solid, physical backup. Not to mention that any computer can experience hard drive failure, and the loss of data or important documents can be potentially devastating. Unless you have the highest-end computer, most models simply don’t have enough storage space, and even the 1 terabyte of storage you get in-game systems like the PS4 or Xbox One max out before you know it.
No matter your specific reason for seeking out an external hard drive-security, portability, storage capacity-you have more options than you may realize.
