Now that the next generation of professional cameras is here, next-gen memory cards have arrived as well in the form of CFexpress cards. These memory cards are currently the fastest memory cards on the market and serve as the successor to XQD memory cards.
The best models offer write speeds of up to 1,480 MB/s and read speeds of 1,750 MB/s. This is approximately three times faster than what XQD memory cards could offer. Cameras that support XQD cards are rolling out updates that allow them to accept CFexpress cards as well, opening the doors to even faster frame rates.
Modern cameras such as the Nikon Z6 and Z7 offer higher resolutions and an increase in color bit depth over their predecessors, making CFexpress cards, and the higher speeds they offer, a necessity to accommodate this. By upgrading from XQD to a CFexpress card, photographers can ensure that their shots are never lagging and the frame rate is always high.
With that said, here are the top CFexpress cards currently available on the market:
1. SanDisk Extreme PRO CFexpress Card Type B (Overall Winner)

The SanDisk Extreme Pro CFexpress Card Type B. This card offers some of the fastest speeds of any CFexpress card at a total of 1,7000 MB/s read speed and 1,400 MB/s write speed making it perfect for action and sports photography.
In addition, the SanDisk PRO also offers a very low latency with its high-speed recording, which is why it is such a good choice to use for shooting fast-paced action video. The SanDisk PRO can handle RAW 4K video and is fully compatible with XQD cameras.
All in all, the SanDisk PRO is one of the very best CFexpress cards available and will be a solid choice for any photographer.

Finding the Best CFexpress Card
CFexpress cards represent the next generation of memory cards. They offer faster speeds to accommodate the higher resolutions of newer cameras. It’s rumored that the next generation of Xbox will be compatible with CFexpress, in addition to the current and next generations of cameras from Canon and Nikon.
In other words, CFexpress cards are going to become ubiquitous. In the near future, it is very likely that we will see CFexpress cards with PCIe 4.0 rather than their current PCI express 3.0, which will enable these cards to capture even higher resolution and frame rates and be able to handle greater sensor output.
For now, any of the CFexpress cards that we have taken a look at today represents a fast, solid option for your camera.
