Cobalt type CF express

This is a pro level card! Works amazing with Nikon Z8! Best for 4k and 8k! Blazing fast! Different league. One thing to note, little uncomfortable with the cards getting hot, but i am sure its taken into account!

It's ProGrade or Nothing at All

Don't be fooled by the other brands that advertise speed and don't deliver, this card delivers just as advertised and is a must for professional grade gear.
