Review on High-Performance 256GB CFast2.0 CinemaPro CFX310 Memory Card - 530MB/s Read Speed - for Blackmagic URSA Mini, Canon XC10/1D X Mark II and More by Robert Carlson

I would give 5 stars if the reading speed was closer to the manufacturer's specification. They required 330 writes and I kept falling to a low 300 after writing different codecs and two different hard drive speed tests. As a base, I used my Raid 0 editorial drive, which are two 1TB Samsung 850 Pros. I got them for my Ursa Mini Pro with the new BRaw codec, they're easy to find. I plan to buy two more after a month of filming and testing.
