Personal storage device
From Wikipedia, the free encyclopedia
Portable storage devices (PSDs) are small hard drives designed to copy digital photographs (RAW data) from cameras. This is slightly different from a portable media players, which stores music and movies.
They are most often used by photographers to download their digital media cards to a computer. Some are a fixed size hard drive of 20GB, 40GB, 80GB, etc. Newer units are expandable using 2.5" laptop hard drives, allowing for an unlimited amount of storage capability, helpful for video and professional photographers.
When traveling and photographing for long periods of time, a personal storage device may be a useful alternative to backing up or purging memory cards if a computer is unavailable for downloading.
Many PSDs will connect directly to a camera and copy the images, or they may provide a slot for a memory card to plug in, with or without a card reader device. Some early models allow you to review the images on color screens, but at the top end of the market. there are portable media players, which are designed for MP3s and movies as well.
