Believe it or not, it's now almost four years since the CFexpress Type A memory card format broke cover, alongside the launch of the Sony a7S III. Since its introduction, it's been somewhat overshadowed by its faster Type B stablemate, but that's now changing. The latest and greatest Type A cards are built to CFexpress 4.0 spec, which means they're twice as fast as the Type A cards we're used to - this makes Type A 4.0 cards just as quick as a conventional (CFexpress 2.0) Type B card.
