As a security measure, use an external hard drive for storing your existing computer data. Additionally, transferring your files to an external location frees up space so the computer runs faster.
Buyers need at least 1 TB of memory when keeping a comprehensive photo, music, or movie collection. A smaller external hard drive such as 250 GB is adequate storage for routine correspondence and spreadsheets. Keep the portable hard drive in a briefcase to access data on the go.
