The Lexar CFexpress card features next-generation technology that exceeds the transfer speeds required by most mirrorless and DSLR cameras.
In this review I’m taking a look at the 128GB version, but there are four capacity variants in the range which cater for all levels of photographer, from hobbyists right through to photography and video pros.
As with the SD card format, there are several different types of CFexpress, and the Lexar card falls into Type-B, which is the most common for mainstream cameras.
What makes CFexpress 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 impressive.
As it is, the Lexar 128GB CFexpress quotes 1750MB/s read, and 1000MB/s write, that’s more than enough for all compatible cameras on the market at this moment in time.
