In summary, the Exascend CFexpress Type A / SD Express Card Reader is a versatile and high-performance card reader that is designed to meet the needs of professionals who require fast and efficient data transfer. The reader’s dual-slot design, USB-C 3.2 Gen 2 interface, and rugged aluminum casing make it an essential tool for those working in demanding professional photography environments. 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. The Sony MRW-G1 CFexpress Type B/XQD Memory Card Reader also comes with both USB Type-C to Type-C and USB Type-C to Type-A cables, making it compatible with a wide range of devices. This is particularly useful for those who work with a variety of different computers and devices and need a card reader that can work with all of them. With many current high-end cameras now utilizing both the CFexpress and SD card formats, it makes sense to get a card reader that also takes both standards. This offering from Prograde Digital is a high quality choice and an ideal match for today's mirrorless and DSLR cameras.

CFexpress cards come in three types: A, B, and C. Types A and C are the newest cards, introduced in 2019. As of early 2022, you can only buy type A and B memory cards, and cameras currently being sold use one of the two. Sony's A1, for example, accommodates type A, and Nikon's Z7 supports type B. 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. No. Where many cameras today are built to accommodate SD cards, CFexpress cards are still being worked into the rotation. Each type of CFexpress card is also a different size. Type A cards are a little smaller than conventional SD cards, while type B are the same size as XQD memory cards. Type C cards are even bigger than old-school compact flash cards.
Buying Guide
In conducting the tests for the cards hooked up to a computer, we saw some very strange results, eventually figuring out that major differences would be introduced not only by using different card readers, but also even which port we chose to hook it up to on the computer, and also what sort of cord was used. These results retested, standardized on a Sonnet dual CFexpress card reader using a Thunderbolt 3 port and cord. Tests were limited to two R5 bodies and one sample each of all of the cards, except the Delkin, where we were able to get an early copy of the 512 GB version with the new firmware. Both Delkin cards performed similarly. Regarding the low sample sizes, the consistency between bodies makes me confident they aren’t introducing bias, but an anomalous performer among the cards would definitely goof up the results. The problems noted above can be solved with the use of either the Delkin or the Angelbird card readers, which each work fine with all 10 cards tested. Methodology 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.

We tested using repeated real-world transfers of a large folder of image files (multiple small files will always take longer to copy/paste than a single video of the same total file size), as well as a single large 4K video file, to determine the maximum possible real-world sustained transfer speeds you're likely to achieve. Finally, to test theoretical maximum possible transfer speeds of the card, we used CrystalDiskMark's storage benchmarking software, specifically the sequential read/write setting. 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. Here’s the breakdown of prices as of mid-September 2020 at B&H… Many card readers now connect to your computer using a USB-C plug, but adapters are readily available to convert to normal USB. So what are they? Do you need them? Are they really that great? We'll start by looking at just what makes CFexpress cards so special. What Are CFexpress Cards and Why Should I Care?
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. Many of us other R5 owners were puzzled by this, as the spooling-up time seemed to be impressively short. The RDE2 card reader is equipped with a CFexpress Type B card slot, which is a popular type of card used in professional cameras. It is worth noting that this card reader is not compatible with XQD memory cards.

Almost all cameras that originally supported XQD cards have now been firmware-updated to also work with CFexpress Type B cards, so cameras like the Nikon Z6 and Z7 are no longer restricted to XQD cards alone.Overall, the Delkin Devices CFexpress Type A & UHS-II SDXC Memory Card Reader is a great choice for professionals who need a high-speed and reliable card reader that can handle their demanding workflows while on the go. With its sturdy construction, multiple card slots, and high-speed connectivity, it’s a must-have accessory for any professional photographer or videographer. There is some correlation between drive performance and actual performance in terms of throughput when used in a camera. The chart here shows a comparison of the drive performance (orange) versus the number of frames that can be blasted through the card in 30 seconds on an R5. These numbers are presented as indices, not actual performance metrics. Another important factor when buying any memory card is the card's sustained write speed. Sustained write speed is how fast the card transfers data when being used steadily over a longer period of time --- basically the overall average write speed of the card. In summary, the Lexar Professional CFexpress Type A & SD Dual-Slot USB 3.2 Gen 2 Type-C Card Reader is a versatile, compact, and durable card reader that supports high-speed data transfers for creative professionals on the go. Its support for both CFexpress Type A and SD media cards, along with its stylish and durable design, make it an excellent choice for photographers and videographers who need a reliable card reader for their workflow.

The Delkin Devices CFexpress Type A & UHS-II SDXC Memory Card Reader is a powerful and versatile option for professional photographers and videographers who require a compact and lightweight solution that can handle demanding workflows. The reader features one CFexpress Type A card slot and one UHS-II SDXC card slot, making it capable of handling a wide range of memory cards. The reader is also designed with durability in mind, featuring an anodized aluminum housing that helps to protect it from damage during transport. The CFexpress Type A card slot is covered by a rubber cap to help protect it from dust and debris, and multiple heat sinks are included to help keep the reader cool during extended use. The CFexpress card is relatively new and it is currently the fastest and the most capable memory card format on the market. And I believe the CFexpress card will be the default choice for future-generation stills and video cameras. If you are using a camera with CFexpress Type A/B card slot, you will need a fast CFexpress Type A/B card, and an additional reliable CFexpress Type A/B card reader to ensure faster data transfer speeds.For example, below are the testing numbers from a new Silver edition Lexar 512GB CFexpress card — the same model it announced in August— as processed through Lexar’s latest-generation USB 3.2 card reader: Lexar Silver 512GB CFexpress Card tested through a Lexar USB 3.2 card reader. However, where the Cobalt cards really shine is that ProGrade doesn't just advertise their peak read/write speeds, it actually guarantees the minimum sustained write speed (host device permitting). In this case, that's 1400MB/s - just 100MB/s shy of the 1500MB/s max write rate, which is hugely impressive. Two capacities are offered - 325GB and 650GB - and both are 'reassuringly' expensive for their size, but when has top performance ever been cheap? USB 3.1 Gen 2 is twice as fast than Gen 1, but few readers use it, and even fewer memory cards are fast enough to exploit Gen 2. Sony's CFexpress Type A/SD Card Reader was launched at the same time as the Sony a7S III's release, as this was the first camera to utilize the CFexpress Type A memory card format (the physically larger Type B cards already being commonplace). The Exascend CFexpress Type A / SD Express Card Reader is also designed for convenience. With its dual-slot design, users can easily move files between different camera systems without the need for multiple card readers. The reader is compatible with SDXC/SDHC/SDUC/SD cards, ensuring that it can work with a wide range of devices.
