purchases can be made easily through the company’s ecommerce site.
ProGrade Digital cards and readers will be available for purchase by the
general public as soon as firmware for existing compatible cameras is
updated or when new devices are introduced into the market.

“Having demonstrated the capabilities with CFexpress early last year,
ProGrade Digital is pleased to invite development partners globally to
evaluate this new card standard for use with their next generation
products,” said Wes Brewer, founder and CEO of ProGrade Digital. “The
CFexpress form factor provides extremely fast data read and write speeds
with very low latency, which makes it ideal for imaging, as well as a
range of industrial, computational and enterprise applications. Our new
CFexpress high speed USB 3.1, Gen 2 reader, adds immediate access of
high-speed data transfers from camera to any workstation utilizing
commonly available USB ports. Through our new sampling program, plus our
ongoing work with imaging industry leaders, ProGrade Digital continues
to advance the market adoption of this important new standard for
removable storage.”
