This card reader sports the classic combo of SD and CompactFlash slots, both being the fastest of their type - UHS-II, and UDMA 7. You can use both simultaneously, and the case’s design means a card of each type can be stored inside the reader, protected by a hinged rubber door that closes around them.
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. In conclusion, CFexpress Type A card readers have become increasingly important for professional photographers and videographers who require fast and reliable data transfer speeds. After reviewing several options, the ProGrade Digital CFexpress Type A & UHS-II SDXC Card Reader, Sony MRW-G2 CFexpress Type ASD Memory Card Reader, and Delkin Devices CFexpress Type A & UHS-II SDXC Memory Card Reader stood out as the top three choices.Smooth and efficient workflow is all that is needed in day to day activities of taking videos, transferring them and pictures too.

This may save you some reading, but it’ll certainly cause some squinting. We’ve titled this cityscape of a chart “Downtown CFexpressville.” When looking at online forum discussions for Canon EOS R5 performance, we noticed that several people seemed to think that the R5 had a terribly long initial startup time, making it inconvenient for action and wildlife photographers.

In the course of comparing cards, we discovered two genuine bugs. In talking these over with the manufacturers, we were surprised to see them being very open about this, with them asking specific questions to help narrow down the problem. The two manufacturers, Delkin and Angelbird, were not apprised of the fact we were reviewing the cards and were treating us as just another customer.
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.

UHS-II SD cards are faster, and all the readers here are compatible. UHS-I card readers will read UHS-II cards, just slower. The card that clears the buffer the fastest is the SanDisk Extreme Pro 512GB, clearing it more than half a second faster than the other cards of its capacity. [Note the late entry of the Lexar Professional 512 GB card after this article was written upset this record, but both are fantastic at clearing cache.]
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. Price mattered to start, of course, but when you figure out that the performance on these cards is pretty consistently good, price takes on even greater importance as a differentiator.

The 90cm USB Type-A lead is hardwired to the reader, so while you won’t lose it, it can be slightly awkward for transportation, and you’ll need an adapter to connect this reader to a laptop like the current MacBook Pro. A critical factor – perhaps the most important for sports and wildlife shooters – is the number of shots you can rip before you get the unpredictable stutter of a full cache. In mechanical shutter at 12 FPS, the R5 will give you between 10 and 15 seconds of glorious, uninterrupted shooting. This is the sum of the buffer and the number of shots a card can manage to ingest while the buffer is filling. The Delkin consistently took the lead here.
