CF express B cards have sustained write speeds between 800 and 1500 MB/s. To clear a 70 shot buffer of 100MB files should take less than 10 seconds. The 20+ seconds currently being demonstrated indicates a pretty severe bottleneck writing to the card. Kind of negates the point of the slot, and the extra cost to the consumer of buying the cards.I doubt that this will be fixed. It seems that Panasonic has with the S1Rii the same buffer process as with the Lumix G9ii. The camera shoots first the images and only after the buffer is fulll, it starts writing to the card.
