What is the Lexar CFExpress Type B Card Gold 2TB?

The Lexar Professional CFexpress Type B Card GOLD 2TB is a cutting-edge memory card designed to meet the increasing demands of high-speed data transfer in high-end cameras and camcorders. This card is specifically designed for professional videographers and content creators who require massive storage capacities and efficient high-resolution video capture. While photographers can use this card there are smaller capacity versions that would be cheaper and should have more than enough capacity for most uses.

CFexpress Type B cards use the PCIe 3.0 and NVMe interfaces to achieve transfer speeds of up to 2000MB/s, which is significantly faster than previous memory card standards, such as SD or CompactFlash, SD UHS-II max out as 600MB/s. The Lexar GOLD 2TB card offers a minimum sustained write speed of 1500 MB/s, enabling seamless video recording from start to finish.

Camera manufacturers like Canon and Nikon already produce cameras that support the Type-B format, while Sony has opted for the physically more compact Type-A. Either way, CFexpress cards mark a major leap forward in storage technology, and the Lexar Professional CFexpress Type B Card GOLD 2TB is currently one of the largest and fastest cards available.
