Overall, the ProGrade Digital CFexpress Type A & UHS-II SDXC Dual-Slot USB 3.2 Gen 2 Card Reader is an excellent choice for those looking for an affordable and high-speed memory card reader that can handle both CFexpress Type A and UHS-II SDXC memory cards. Its competitive price, sturdy build quality, and easy-to-use design make it a great option for professional photographers and videographers.
This is a device that has been designed in a unique manner to ensure that you are allowed to ingest, edit and even reach the extent of archiving any content that you have made in a creative manner. It is one of the greatest because it ensures that this is all done with the best known speeds of the content. The metal closure is one that is rugged hence ensuring durability and also longevity. We highly recommend this as the top best XQD card reader for 4K video workflow. CFexpress Type A cards first appeared on the market when Sony launched the a7S III mirrorless camera. Sony has continued to add compatibility for this card type to their new camera models, including the Sony a7R V, Sony a1, Sony a7 IV and the Sony FX30, FX3, FX6 Cinema cameras. Other camera manufacturers are likely to follow suit, making CFexpress Type A cards a more prevalent choice in the industry.Below, is a table of the claimed maximum write and read speeds of the cards. As discussed earlier, dynamic heat reactions prevent there being a real minimum write speed figure, but even so, these maximum speeds show the manufacturers being pretty generous with themselves. These numbers are an industry convention that doesn’t have a great deal to do with actual card performance. To round out the table, we added a couple of additional rows with information just slightly more useful than the marketing claims. It should be said that each of these cards has a different shooting rhythm style. The Sony 512 has a pleasing, consistent rhythm to the shots, shooting roughly equal amounts on and off after filling the buffer. The Lexar is a big more syncopated, perhaps less predictable. The Angelbird and ProGrade cards create more tension, with a spattery non-pattern. You never really know in which tenth of a second the shutter will start up again, or for how long.
Speed wise, we could only extract a max video read speed of 223MB/s and 198MB/s write rate from our UHS-II SD card - not awful, but some way shot of some other readers we've tested. Image transfer performance is worse still, with 152MB/s read and 98MB/s write speeds being slower than average. The CFexpress standard, as interpreted by camera manufacturers, is still being established in implementation, so we can expect issues to crop up as new cameras are introduced and firmware needs to be adapted. There is no amount of testing that would solve the issue of a third party camera maker launching a camera with a slightly different protocol interpretation a year later, so all manufacturers are likely as vulnerable to this problem as all the others.
The ProGrade Digital CFexpress Type A & UHS-II SDXC Card Reader offers exceptional performance, reliability, and convenience with its dual slots, compatibility with various cards, and rugged design. The Sony MRW-G2 CFexpress Type ASD Memory Card Reader delivers lightning-fast data transfer speeds and is ideal for professional photographers and videographers. Lastly, the Delkin Devices CFexpress Type A & UHS-II SDXC Memory Card Reader is a compact and portable reader that is designed to handle high-performance industry demands, making it perfect for on-the-go professionals. Supports USB 3. 1 Gen2 speeds for smooth, efficient workflow from location to post production* | *USB 3. 1 Gen 2 permits interface speeds of up to 1250MB/s. Actual performance may vary based on memory card, host device, file attributes, usage conditions and other factors. Relative to one another, the cards in the same class as one another showed only about 10 percent variance in performance. There certainly is shown a different set of classes, though, when looking at the 128 GB and 256 GB cards versus the higher capacity models. Those smaller cards get a roughly 20 percent performance hit on average. So, with everything performing at a very, very high level, and little variation among them, factors like price and service weigh heavily.
