P2 (P2 is a short form for "Professional Plug-In") is a professional digital recording solid-state memory storage media format introduced by Panasonic in 2004. The P2 card is essentially a RAID of Secure Digital (SD) memory cards with an LSI controller tightly packaged in a die-cast PC Card (formerly PCMCIA) enclosure. The system includes cameras, decks as drop-in replacements for videotape decks, and a special 5.25-inch computer drive for random-access integration with non-linear editing systems (NLE). The cards can also be used directly where a PC card (PCMCIA) slot is available, as in most older notebook computers, as a normal hard disk drive, although a custom software driver must first be loaded.

As of 2015, P2 cards are currently available in capacities of 30 and 60 GB. At introduction, P2 cards offered low recording capacity compared to competing, video tape-based formats (a miniDV tape holds roughly 13 GB of data, and an S-size HDCAM tape holds 50 GB). To solve this, camcorders and decks using P2 media employ multiple card slots, with the ability to span the recording over all slots.

P2 cards are of a ruggedized PCMCIA type with the fastest transfer speeds currently available through this format. The card also contains a processor that organizes and safeguards the files and the case is developed and crafted to "military" (according to Panasonic) specifications, making P2 cards tough and reliable.

The first pieces of equipment released by Panasonic which used the P2 format included the AJ-SPX800 (a 2/3" broadcast camcorder for ENG and EFP applications), the studio recorder AJ-SPD850, the AJ-PCD10 offload device (basically, a five-slot PC card reader with USB interface designed to fit a 5-1/4" IT systems bay), and the memory cards themselves – AJ-P2C004 (4 GB) and AJ-P2C002 (2 GB). Panasonic is currently shipping a wide range of camcorders that support the P2 format. Panasonic also announced the P2-based AG-HPX170 handheld HD tapeless camcorder. The HPX170 is very similar to the HVX200 and the HVX200A, the main difference being the lack of a video tape drive on the HPX170.

On April 15, 2012, Panasonic introduced the "MicroP2" system, an entirely different format based on SDHC/SDXC conforming to UHS-II (Ultra-High Speed) bus mode.[1][2] Most (but not all) current P2 products can use MicroP2 (UHS-II) and SDHC/SDXC (UHS-I/UHS-II) cards through a MicroP2 card adapter, with some requiring a firmware update. Some P2 products (such as the AG-HPX500E camera) are not able to use MicroP2 at all.

On February 27, 2014, Panasonic announced a new generation of P2 media, the expressP2 card, designed to accommodate high frame rate 1080 HDAVC-ULTRA recording (above 60fps) as well as 4K capture.[3]
