The expressP2 Cards are designed to accommodate high frame rate 1080 HD AVC-ULTRA recording (above 60fps) as well as 4K capture from the 4K VariCam LT, the 4K VariCam 35 and the 2/3 type VariCam HS (High Speed) camera/recorders.
The expressP2 Cards facilitate the recording of 4K video at frame rates up to 120p as well as the 2/3 type VariCam HS’s 1080 HD recording at frame rates to 240fps. In addition, the expressP2 Cards ensures high-speed transfer, high reliability and the writing assurance of all P2 frame rates, formats and codecs. An expressP2 Card is the same length and width as a standard P2 Card, but has 1,5x the thickness.
The expressP2 Card offers extremely fast transfer speeds of up to 10.0Gbps (limited to 2.4Gbps when using the XPD1) and contains a flash memory error correction system, equivalent to a RAID system, to recover from a failure in a sector, page, or entire block.
