Hard drives (HDDs) and solid-state drives (SSDs) are able to hold a lot more storage than the average USB. This is a fairly simple way to add extra storage to your PC without needing to open it up or fiddle with the operating system. Depending on your PC, you may be able to install a new internal HDD or SSD. However, it's more common (and much easier) to add more space by connecting an external SSD or HDD to your computer's USB port. You can opt to keep videos, photos, and other large files on the hard drive for safekeeping.^{[3]
