The new CFexpress 4.0 specification promises significantly faster transfer speeds than the cards currently on the market and while no camera can take advantage of it right now, your computer can, which makes a strong case for consolidating your storage hardware into a single media.
CFexpress 4.0 cards are already entering the market this year with the promise of much faster read and write speeds. While that sounds great, it is going to be a while before photographers and filmmakers can really take advantage of it.
The CompactFlash Association today announced the specification for CFexpress 4.0 which can double the theoretical throughput performance compared to current cards while maintaining backward compatibility.
If you’re a photographer, you’re likely familiar with memory cards. They’re what our photographs are stored on -- removable flash media that we insert into a slot (or slots) in our camera, take photos, and then (sometimes) remove and insert into a card reader or card slot on our computer.
