Kingston says the reader gets better performance when used with Kingston memory cards, but it is compatible with SD and micro SD cards from all manufacturers. UHS-II SD cards are faster, and all the readers here are compatible. UHS-I card readers will read UHS-II cards, just slower. If you shoot video, or if you photograph sports, news or other fast-moving events, XQD is the memory card format for you. The compact device boasts a durable design with rubber covers on the end to help protect it from being dropped. This also means you can safely store your CFexpress card inside. Access firmware update capabilities when used in combination with an Angelbird CFexpress Type B Card to update firmware at the card level to maintain on-going camera compatibility and full features set for the lifespan of the card.

It also has a durable plastic construction and both SD and XQD cards slip in smoothly. Most importantly, the supplied cable creates a reliable connection to a computer and images transfer swiftly. 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. Testing with a UHS-II SD card yielded highly respectable video transfer speeds of 252MB/s read and 210MB/s write - not far off the much more expensive ProGrade Digital USB 3.1 Gen 2 Dual-Slot Card Reader. 202MB/s read and 107MB/s write figures in our testing when shifting images are also superb. The market for CFexpress Type A card readers is still relatively new, and the options are somewhat limited. However, there are several models available that offer impressive transfer speeds and convenient features to help streamline your workflow. Boasting max read/write speeds of 1730/1540MB/s respectively, you'll be hard-pressed to find a faster CFexpress card. What's more, with capacities ranging from 128GB right up to a humongous 2TB, there's sure to be a Delkin Power CFexpress card to suit your storage needs and budget.It has to be said that the CFexpress format is a leap forward. The cards are all so fast that the difference between the top performer in clearing a full buffer and the card that came in second from last is just 1.5 seconds. The buffer is that on-board, super-fast memory that fills up, and then you’re just left with the raw speed of your memory card, chewing through what the buffer can upload to it. In my own speed tests, the ProGrade Digital CFexpress Type A reader consistently outperformed the Sony MRW-G2. I often saw speeds in excess of 820MB/s for read speeds, which is remarkable given that the Sony card I used for testing only claimed a max of 800MB/s. Repeated tests made it clear to me that the ProGrade Digital reader is much faster. This is an excellent result considering that it is quite a lot cheaper. Conclusion 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. 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.

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 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. Lexar’s CFexpress card reader enables read speeds of up to 1050MB/s, allowing the speedy transfer of files from card to your machine. What makes CFexpress memory cards so special is the PCIe 3.0 interface technology which provides 1 GB/s data transfer per lane. Type B features two lanes, so theoretically you could be looking at 2GB/s transfer speeds which is very impressive. With USB 3.1 Gen2 speeds 3 the SanDisk Extreme PRO® CFexpress® Card Reader optimizes the performance of the CFexpress® Card Type B 2 for smooth, efficient workflow from location to post production.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. Many card readers now connect to your computer using a USB-C plug, but adapters are readily available to convert to normal USB. Designed to connect with the latest laptops and devices, the CFexpress® Card Reader is ready for the newest USB-C™ technology. Compared to ProGrade's top-end Cobalt CFexpress cards, the cheaper Gold product line looks very tempting, as they're rated for the same 1700MB/s max read speed, and their 1400MB/s max write rate is just 100MB/s down on the Cobalt. 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.

I tested the speed of the MRW-G2 using one of Sony’s TOUGH 160GB CFexpress Type-A cards, and was able to achieve speeds of around 570MB/s for write, and 757MB/s for reads. Considering the theoretical maximum read speed of those cars is 800MB/s, this falls into what I would consider to be “very good performance” terriroty. ProGrade Digital CFexpress Type A & UHS-II SDXC Dual-Slot Reader If you want the most number of shots in 30 seconds, you’ll have the Angelbird 660GB XT. But it’s best by only 1 picture out of 337, and it has an odd behavior of causing camera startup to take 4 more seconds than any other card. This will be a deal-breaker for some. XQD is a memory card format that was developed earlier this decade as a successor to CompactFlash cards. XQD cards are designed for professional uses, such as recording video or shooting sequences of images in your camera’s burst mode. 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.

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. To provide greater flexibility and a more organized workspace, the CFexpress® Card Reader comes with a .5 meter USB-C™ cable. 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.

The Sony MRW-G2 CFexpress Type A/SD Memory Card Reader is a professional-grade memory card reader that offers exceptional speed and versatility. Designed specifically for CFexpress Type A memory cards as well as SD/SDHC/SDXC card types, this card reader is built to handle the demands of high-resolution image files, 4K/8K videos, and other high-volume data. In terms of build quality, the Sony MRW-G2 is built to an exceptional standard. It feels “pro” in every way, with a solid metal construction that exudes durability and reliability. This is further complemented by the inclusion of both USB Type-C to Type-C and USB Type-C to Type-A cables, ensuring maximum compatibility with your devices. At least the USB 3.1 Gen 2 (10 Gbps) interface is speedy, equating to a maximum transfer speed of 1250 megabytes per second. However, even this is still some way short of the 1700+MB/s read speed that the best CFexpress cards can manage. even this can't let the fastest CFexpress Type B cards run at max speed. 5 things to look for in a card reader In addition, all Lexar product designs undergo extensive testing in the Lexar Quality Labs to ensure performance, quality, compatibility, and reliability, providing peace of mind for professionals who rely on their equipment.But this may well be no fault of the card, or indeed Sandisk's marketing department. While the physical hardware of CFexpress is doubtless capable of such stunning performance, other limiting factors inevitably come into play. A computer's operating system, the type, size and quantity of files being transferred, the connection between card and computer, and finally the computer's internal mass storage device (SSD or HDD) will all play a part in determining the maximum file transfer speed you can achieve.
