San Jose, CA April 21, 2025, 8:00 am PT — ProGrade Digital, Inc., founded with a mission to provide the highest quality professional grade digital memory cards, solid state drives, hubs, and workflow solutions, announces its new line of SDXC V90 memory cards in the Iridium product line. These higher-performance cards offer a read speed of up to 300MB/s, a write speed of 200MB/s (128GB) and 275MB/s (256GB, 512GB, and 1TB), and a minimum sustained write speed of 90MB/s. The SDXC UHS-II, U3, Class 10, V90 Iridium cards offer optimal performance for digital cinema cameras, upper-end DSLR, and mirrorless cameras, which produce incredibly rich data streams and require greater capacity from a memory card.
“Our new premium SD Iridium line of V90 cards completes our transition out of the older Cobalt line,” says Josh Brewer, Product Manager at ProGrade Digital. “The Iridium line is based on a new NAND and Controller architecture that improves the price-performance value, making it an excellent choice for customers seeking the highest performance SD cards from ProGrade.” It will be available for purchase at the beginning of May.
