Hi all

64GB KingSpec CFast Memory Card 600X Speed Rating (up to 277MB/sec) KCF-SA.7-064MJ: Amazon.co.uk: Computers & Accessories (http://www.amazon.co.uk/KingSpec-CFast-Memory-Rating-KCF-SA-7-064MJ/dp/B00Z0Z91VO/ref=sr_1_1?ie=UTF8&qid=1459158063&sr=8-1&keywords=CFast+card+64gb)

The card that came with my Ninja Star is an Atomos CFast 1.0 80 mb/s

This card states write speed up to 79 bm/s

Anyone care to weigh in?

Pete

So the card will write up to 79MBps, but what is its averaget write speed? Does it ever drop well below that 79MBps? Will it ever drop lower than the data rate required to write ProRes data to it?
