Lexar 128 GB CFexpress Card Specificationsīelow are the specifications of the card: The serial number of the memory card is displayed on the front side. The memory card features an aluminum chassis with some labels (including a label that says “Lexar, an affiliate of Longsys, a Chinese company”), while the top plastic cover has the main label that shows the memory card capacity, CFexpress Type B logo, 1750 MB/sec read speed, as well as “Lexar Professional” logo (exactly as shown in the image above).
The build quality of the Lexar 128 GB CFexpress card is excellent. Per its specifications, the card is capable of 1750 MB/sec read and 1000 MB/sec write speeds, which is insane! Compare that to the fastest XQD memory cards available today that max out at 440 MB/sec read and 400 MB/sec write speeds and you will see why CFexpress is so much better technically. The Lexar 128 GB CFexpress memory card is a “Type B” memory card based on the CFexpress 2.0 version and PCIe 3.0 x4 bus.
