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. 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. 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.] 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 correlation between drive performance and camera performance is inconsistent for some cards. This may have to do with firmware differences. Some smaller-than-512 GB cards seem to have similar performance between functioning as a drive on a computer and functioning as a memory card in the camera, where the others show much better performance when used as a drive.

Smooth and efficient workflow is all that is needed in day to day activities of taking videos, transferring them and pictures too. What should be noted also is that the actual performance will also vary depending on the device that will be used. Don’t let the action go, snap it and record it. It never fails users and when you have it, then you are sure that everything you have planned will just go as planned UGREEN SD Card Reader USB 3.0 Card Hub Adapter 5Gbps Read 4 Cards Simultaneously If you’ve recently invested in a camera with an XQD card slot, or XQD and SD cards slots, the Sony MRW-E90 XQD/SD Card Reader could be a good addition to your kit.

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. 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. 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. Lexar’s CFexpress card reader enables read speeds of up to 1050MB/s, allowing the speedy transfer of files from card to your machine.

As with the SD card format, there are several different types of CFexpress memory cards. CFexpress Type-B which is the most common for mainstream cameras. This change in memory card type means that many photographers are having to change their memory card reader. The Sony MRW-E90 XQD/SD card reader is an attractive option as it has two slots, one for XQD cards and the other for SD-type media.

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.
