Tested in mirrorless and DSLR bodies, the card's claimed sustained minimum write of 90MB\/s and peak read of 300MB\/s make it an obvious pick when clearing buffers quickly and offloading large files is a priority. The review examines real-world usability, compatibility, and the card's quality control features.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eRead speed up to 300 MB\/s:\u003c\/strong\u003e Enables fast off-loads to a workstation so photographers spend less time waiting between shoots.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eWrite speed up to 275 MB\/s with 90 MB\/s sustained:\u003c\/strong\u003e Provides consistent performance for continuous 4K\/8K and RAW recording without dropped frames.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eUHS-II V90 and U3 class:\u003c\/strong\u003e Ensures the card meets high video recording standards for cinema and high-bitrate codecs.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRigorous quality control:\u003c\/strong\u003e Serialized testing and 100% card testing reduce the chance of variants or early failures in production runs.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eRefresh Pro support and warranty:\u003c\/strong\u003e ProGrade's refresh software and a three year warranty help maintain long-term performance and give added peace of mind.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe card is aimed at professional and enthusiast content creators shooting sustained high-bitrate video or continuous RAW stills in cameras from Canon, Sony, Nikon, Panasonic, Fuji, Olympus and Samsung.
