CompactFlash Association Announces CFexpress 2.0 Specification

As a follow-up to the CFexpress 1.0 specification first revealed in late 2016, the CompactFlash Association has announced the 2.0 update.

The new standard brings two more form factors to CFexpress, both targeting professional imaging and industrial markets. The two new form factors join the original, ushering in Type A, Type B and Type C cards.

CFexpress 2.0 Type A cards are the smallest of the three form factors at 20mm x 28mm x 2.8mm, which is a bit smaller than XQD cards. The Type A cards feature a Gen3 PCIe interface with one lane and a maximum theoretical performance of 1000MB/s.

The Type B card has the same dimensions as XQD cards at 38.5mm x 29.8mm x 3.8mm. This variety has a Gen3 two lane interface and maximum theoretical performance of 2000MB/s.

The Type C form factor is largest at 54mm x 74mm x 4.8mm with a Gen3 four lane interface and maximum theoretical performance of 4000MB/s.

The different form factors offer manufacturers flexibility in choosing which card type their devices will utilize, such as the small card with a priority on compact size instead of transfer speeds, or the largest card with a focus on speed at the expense of compactness.

According to the association, the CFexpress 2.0 specification is designed for a variety of needs, including imaging, which specifically includes DSLRs, mirrorless cameras, drone cameras and video cameras.
