Panasonic announced at the NAB 2008 a new solid state disk with 64GB capacity for its HD recording professional P2 camcorders.

The Panasonic AJ-P2C064 can record more than four hours of DVCPRO footage (64 GB X 4 minutes per GB), or more than two hours of DVCPRO50, AVC-Intra 50 (64 GB X 2 minutes per GB) or 64 minutes of AVC-Intra 100 or DVCPRO HD.
With five 64GB P2 cards installed (see, we talking professional equipment here), an AJ-HPX3000 P2 HD camcorder can record for 5.3 hours in AVC-Intra 100 or DVCPRO HD (6.6 hours in 1080/24pN) and 10.6 hours (13.3 hours in 24pN) in AVC-Intra 50 or DVCPRO50.
The reusable 64GB P2 card is ideal for long-form production and other applications that require long record times.

The 64GB P2 card is scheduled for initial deliveries in fall 2008. The new 64GB P2 card will be offered in addition to the current 32GB and 16GB P2 card.
