P2 (P2 is a short form for "Professional Plug-In") is a professional

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,

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

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 "

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]
