OWC has just started shipping the first available CFexpress 4.0 Type A cards for Sony cameras. While most major memory card manufacturers have unveiled the specifications for their upcoming CFexpress 4.0 Type A cards, the OWC Atlas Pro cards are the first available. You can buy them from the links below:
- OWC Atlas Pro CFexpress 4.0 Type A 960GB – OWC / B&H Photo / Amazon
- OWC Atlas Pro CFexpress 4.0 Type A 480GB – OWC / B&H Photo / Amazon
UPDATE: I have reviewed the OWC Atlas Pro CFexpress 4 Type A cards and a compatible OWC CFexpress 4.0 Card Reader.
The CFexpress 4.0 standard for Type A cards allows for read and write speeds double those available from CFexpress 2.0 Type A cards. While there are currently no cameras designed to take advantage of the 4.0 Type A standard, the cards are backward compatible with all existing Sony cameras using the 2.0 standard.
So, why buy them if there aren’t any cameras that support them yet? This is a no-brainer when all the facts are laid out. Firstly, you’re future-proofing your kit. There will be cameras within the next 12 months that take advantage of CFexpress 4.0 speeds. Secondly, these are actually cheaper per GB than most of the slower, older Type A cards. Thirdly, perhaps most importantly, you can download photos off your memory cards twice as fast as you can with older CFexpress 2.0 Type cards. And that is an advantage right now—no need to wait as long as you have a USB 4.0 CFexpress reader. Who wouldn’t want to halve the time it takes to download their photos?
On that note, OWC includes a CFexpress Type A to Type B converter with its new Type A cards, allowing users to use a single card reader to process downloads from both Type A and Type B cards. Including the Type A to B adapter is all the more impressive when considering the price of OWC’s cards. These are aggressively priced compared to the competition from ProGrade Digital and Lexar.
