The Compact Flash Association has announced that there will be three versions of their new CFexpress format cards. Within the CFexpress 2.0 specification are three versions, designated types A, B, and C. Type B is identical in form to current XQD cards and will be capable of transfers rates of up to 2,000 MB/s. Type A will be smaller for use with compact devices and will have a transfer rate of 1,000 MB/ while type C will be larger and offer 4,000MB/s.

Cameras that have a physical XQD slot will be able to use CFexpress type b cards with a firmware update.
