The reader is optimized for Lexar CFexpress Type A memory cards and SD media cards, making it easy to establish an efficient workflow when transferring high-res photo and video content. The rugged aluminum casing of the Exascend CFexpress Type A / SD Express Card Reader ensures that it is durable and able to withstand the demands of life on the go. Its compact design makes it easy to carry around, while its sturdy construction ensures that it will last. Many card readers now connect to your computer using a USB-C plug, but adapters are readily available to convert to normal USB. These are very, very good numbers by old metrics. So good, it would be poised to unseat the Sony TOUGH CFexpress Type B card that has been PetaPixel‘s recommendation for the last year.

The affordable Delkin surprises here by coming in 8th after winning the buffer test that showed how many uninterrupted frames it could take before the buffer caused skipping. It appears to be a sprinter of a card, perhaps with firmware that is more cautious on heat throttling, but that is just speculation.On the one hand these figures are hugely impressive results that eclipse any other memory card we've ever tested. However, aside from the 1678MB/s theoretical read speed score we achieved, which comes very close to the 1700MB/s claimed by Sandisk, in every other respect our CFexpress card didn't reach its claimed maximum speeds.

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… CFexpress card readers aren’t all that common, or in this case, cheap. Doubly frustrating, as Sony doesn't even include an SD slot to at least give you a little extra versatility (XQD compatibility is included, though that's due to XQD cards being physically interchangeable with CFexpress Type B). 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. 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.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. Temperature did not appear to affect performance – and this was tested – but the tests did not wait for the camera to cool down between each trial which would have been optimal. Instead, we just made sure the temps didn’t exceed 45C. The Transcend RDE2 CFexpress Type B Card Reader has an aluminum body and a non-slip silicone cover, making it wear and scratch-resistant. The card reader is also heat-resistant, making it durable enough to withstand harsh environments. Additionally, the compact size and portability of this card reader make it easy to carry with you wherever you go. Two sets of data were taken at 250 ISO and at 3200 ISO to see if there were relative performance differences with the different sized files (there weren’t any observable). Some of the data averages are rounded to the nearest ten so we don’t mistakenly imply that our precision is better than it actually is.

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? Designed to connect with the latest laptops and devices, the CFexpress® Card Reader is ready for the newest USB-C™ technology. If you want the best price per GB, you’ll have the Delkin Power 512GB, which is also one of the top 5 in performance. The larger versions of these cards are even cheaper per GB; less than half the average price per GB of the other cards.What's the difference between them? Each card has at least one PCIe pipeline built into it, and the more pipelines they have the faster the card will be. Type A cards have one PCIe pipeline and can transfer data at a max speed of 1GB/s (gigabytes per second). Type B has two pipelines, which doubles that speed to 2GB/s. Type C has four pipelines, which doubles that speed again to a whopping 4GB/s. The Exascend CFexpress Type A / SD Express Card Reader is a 2-in-1 card reader that is designed to meet the demands of professional photographers and videographers who require high-speed data transfers while on the go. This card reader features a dedicated CFexpress Type A card slot and a dedicated SDXC card slot with SD Express support, which eliminates the need for multiple card readers when working with different camera systems. The cards that perform best as hard drives hooked up to the computer are the Sony cards. They’ll offload images and video faster than the others.

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 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 Any of these make for a good choice.
