The CompactFlash Association released version 5.0 of the CF specification. The new standard uses a 48-bit addressing system that raises the maximum storage capacity from 137GB to a humongous 144PB (1PB = 1,000 terabytes). Other improvements include more efficiency data transfer, more efficient cleanup of unused space, ATA standard update, optional "Video Performance Guarantee", and new electrical specification to enable easier and better card design.
To help manufacturers and consumers differentiate the new CF5 cards, the CompactFlash Association has created an evolutionary CF5 compatibility mark. Additionally, since the Video Performance Guarantee feature is optional, the CompactFlash Association has created a Video Performance Guarantee compatibility mark that host and card manufactures can use to help end users choose the right card.
