The computer was once only used for a few purposes, so a lot of storage wasn’t necessary. Information was stored on the little space the computer had and on disks. Nowadays, there is much more of a need for storage. Most people’s computers do not have enough room to store all of their pictures, files, music and other files. A great way to expand your storage space is with an external hard drive. You can have it sit right next to your computer and you can access it any time you’d like.
