Portable Storage

A portable storage device (PSD) is a small hard drive designed to hold any kind of digital data. This is slightly different from a portable media player, which stores and plays music and movies.

Some are fixed size hard drives of 256GB, 320GB, etc. Newer units are expandable using 2.5" laptop hard drives, allowing for an unlimited storage capacity, which is useful for video and images.

When travelling, a portable storage device may be a useful alternative to backing up or purging memory cards if a computer is unavailable for downloading
