A portable hard drive or SSD is a do-it-all data device that can (depending on capacity) carry huge libraries of files and share them between PCs, Macs, tablets, and phones. The best external SSD can also hold full system backup files to restore your system’s OS and software in the event of a crash, or let you run programs directly from the drive itself.
