P2, Professional Plug-In, is a tapeless solid state memory format developed by Panasonic. P2 cards offers comparable recording capacity to tape-based media, and disc-based media, but with the added advantage of no moving parts. The P2 card is made up of a series of SD cards, depending on the capacity. Resistant to impact and vibration, shock, dust, and environmental extremes (including temperature changes), the P2 solid-state memory card can transfer data at high speeds without worry about its dependability.
