Designed in parallel with leading-edge camera manufacturers, the SanDisk Extreme PRO CFast 2.0 memory card offers more than twice the shot speed of today’s fastest memory cards. As the world’s first CFast 2.0 memory card, it delivers the speed and capacity professionals need for Full HD recording specifications, including high-definition 4K video recording**. Next level write speeds help you keep up with the new generation of professional cameras and camcorders, while data transfer speeds of up to 450MB/s make your post-production workflow more efficient. And capacities of up to 120GB** give you plenty of room for large RAW image files and the high-quality video that broadcast and cinema demands.

I love it when the camera manufacturers bleat about memory not being fast enough which is why early adopters like Nikon have chosen the fastest card to date for their D4 camera…the Sony XQD card at a mere 180MB/s.

SanDisk announced this card at the end of the year at inter BEE and at 450MB/s this card meets 4K requirements and more. I think the new Panasonic GH4 will adopt this as will the new range of Canon Cinematic cameras as they already use CF cards.

Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.

One thought on ““CFast” the future of digital 4K recording

  1. So at full speed you can store just over 4 minutes of footage on the card!? Or course this write speed is of no use to most of us here and now. The read speed is more useful as you can easily edit straight off the card.
