ProGrade Digital CFexpress™ 4.0 Type A Memory Card (960GB) Iridium

So far, we have been very pleased with the performance. Very easy to use, the value for money compared to the uhs-ii variant means you get a lower price per Gig.Secondary to that, the speeds are phenomenal, this is being used on the A7RV and even though we will take hundreds of shots per shoot, the buffer speed, copy speed and size all mean that we never have to worry.No complaints, I do of course feel like anyone that this storage medium is very expensive for what it is, but that is not a problem specific to ProGrade who have delivered the best “bang for buck” version of this product.
