Lexar Fly microSDXC Cards for Camera Drones and 1900 MB/s CFexpress Cards Pictured
The new Lexar Professional series CFexpress type-A cards come in capacities of up to 320 GB, with transfer rates of up to 900 MB/s and 400 MB/s guaranteed write-speeds. The larger CFexpress type-B cards can be as large as 2 TB in size, with transfer-speeds of up to 1900 MB/s and 400 MB/s guaranteed writes (the 400 MB/s figure is an arbitrary industry standard to ensure a particular format of video recording doesn’t run into media-write errors). The more premium Lexar Professional Gold series are being targeted at 8K RAW video recording rigs (the latest crop of ARRI and Red cameras), supporting XQD, 1900 MB/s max reads, and 1500 MB/s max writes. Both the type-A and type-B formats come in capacities of up to 2 TB.
At the absolute top of the stack are the Lexar Professional Diamond series, targeting the same market of 8K RAW video recording as the Gold series, but with VPG400 support, and 1700 MB/s maximum write speeds, giving filmmakers headroom for even higher frame-rates and upcoming color and HDR standards. The only trade-off is capacity, and both formats of the cards only come in sizes of up to 512 GB.
