What is the difference between CFexpress 2.0 and 4.0 memory cards?

CFexpress 4.0 cards are engineered to operate on advanced PCIe Gen 4 interface, effectively doubling the bandwidth compared to the previous CFexpress 2.0 standards.

This allows them to set a new benchmark with maximum speeds reaching 4GB/s for Type B and 2GB/s for Type A cards.

Is CFexpress 4.0 backward compatible with CFexpress 2.0?

Yes, CFexpress 4.0 cards maintain full backward compatibility with CFexpress 2.0.

What is the difference between CFexpress Type A and Type B?

CFexpress Type A and CFexpress Type B memory cards are both PCIe-based, although their physical dimensions and transfer speeds differ. CFexpress Type B measures 29.8mm(Width)*38.5mm(Height)*3.8mm(Thickness), whereas CFexpress Type A measures 20mm(Width) x 28mm(Height) x 2.8mm(Thickness).

A Type B card is capable of transferring data at twice the speed of a Type A card.

Which cameras use CFexpress Type B cards?

Some current cameras with CFexpress Type B card slots include:

Nikon Z6/Z7
Nikon Z6 II/Z7 II
Nikon Z8
Nikon Z9
Nikon D6
Nikon D850
Canon EOS R5
Canon C500 Mark II
Canon EOS-1D X Mark III
Canon EOS R3
Panasonic Lumix S1 / S1R
Fujifilm GFX100 II
Fujifilm X-H2S / X-H2

Do you also offer a CFexpress 4.0 memory card reader?

Currently, we offer a single-slot 20 Gbps CFexpress Type B reader, which delivers 2,000 MB/s transfer speeds. We are also launching a 40 Gbps CFexpress 4.0 Type B reader very soon.

Can I use my CFexpress Type B card in an XQD slot?

For cameras with XQD slots, a firmware upgrade is required to enable CFexpress compatibility. Please check your host device’s compatibility with your camera manufacturer.
