About ProGrade Digital

Wes Brewer

Founder and CEO, ProGrade Digital

Whether you shoot with a DSLR, camcorder or digital cinema camera, we have the memory cards that match your requirements for performance, quality and reliability.

The founders of ProGrade Digital are industry veterans in the removable storage and digital photography industries. Each, having spent time at leading companies such as Lexar and SanDisk, brings extensive expertise in the design, development and manufacture of digital storage products, plus longstanding relationships with key manufacturing and supply chain partners. The company focuses exclusively on development of memory cards, card readers and workflow software for professional imaging markets. Flagship products, ProGrade Digital CFast™ 2.0 and ProGrade Digital SDXC™ UHS-II, are optimized to render maximum performance when paired with high-end DSLR, mirrorless, ­­­camcorder and digital cinema cameras from manufacturers such as Canon™, Nikon™, Panasonic™, Sony™ and Blackmagic™. ProGrade Digital memory cards expand the creative visions of cinema and photography professionals around the world.

What’s the difference?


Professional photographers tend to be meticulous about their cameras and equipment since their livelihoods, client trust and reputations are riding on how well their gear performs. ProGrade Digital understands these stringent requirements, and offers memory cards and workflow readers with the performance, quality and reliability that professionals demand.


ProGrade Digital leverages years of experience working closely with professional DSLR and video camera manufacturers to ensure that all cards meet rigorous compatibility and qualification tests. In compatibility testing labs we verify that cards operate within thousands of different camera models. We ensure that cards meet quality compliance to the manufacturers’ requirements, and cards are verified to operate with specific camera models. All ProGrade Digital cards are built to meet the industry standards of the SDA or CFA.


ProGrade Digital performs comprehensive card testing prior to leaving the factory to ensure the lowest possible field failure rate. This is a far more time-consuming and rigorous process than sample testing done by other card manufacturers. By the time our cards hit the market, they have gone through hours of testing. You can have the highest level of assurance that your card will perform flawlessly.

About SDA

The SD Association (SDA) was founded by Panasonic, SanDisk Corporation and Toshiba Corporation in January 2000 as a new industry-wide organization to develop and promote memory card storage standards. Today, the SD Association has approximately 900 members involved in the design and development of SD standards.

SD standards are used by hundreds of brands across dozens of product categories, such as digital cameras, televisions, personal navigation devices, mobile phones, smart phones, automobiles, computers of all types and video cameras, to name just a few. There are thousands of device models using SD standards today.

The very small memory cards, developed to SD standards, have become the most popular portable storage cards in the world.
