The Novachips Express CFexpress 4.0 Type A Memory Cards have always performed very well in the camera's that we have tested them in, matching and surpassing much more expensive Type A cards.
There are currently 3 different capacities of the Novachips Express Type A card available. The write and read speeds vary a little but our in-camera tests show there is very little difference in performance in-camera between the 1.6TB and the slower 400GB cards.

FAQs
Where are Novachips memory cards made?
Novachips memory cards are deisgned and manufactured in South Korea.
What is the difference between CFexpress Type A 2.0 and 4.0?
The main difference is speed. CFexpress Type A 4.0 cards utilize the PCIe Gen 4 bus which delivers twice the bandwidth (up to 2 GB/s) compared to CFexpress 2.0 Type A cards that utilize the PCIe Gen 3 bus (up to 1 GB/s).
CFexpress Type A 4.0 cards are backward compatible with CFexpress 2.0 devices, meaning a 4.0 card will work in a 2.0 camera or reader, but the performance will be limited to CFexpress A 2.0 speeds. Similarly, a CFexpress A 2.0 card will perform at its peak in a CFexpress 4.0 device.
