ProGrade Digital has launched a new Cobalt series UHS-II SD card, which not only meets the V90 standard, but also has a capacity of 512GB.
In 2022, memory cards have entered the military competition, whether it is CFexpress or SD capacity, read and write speed continues to improve. ProGrade Digital said that its newly launched UHS-II SD card belongs to the Cobalt series, of which the maximum capacity of the SDXC UHS-II V90 512GB not only meets the V90 standard, but also continues to be no less than 90 MB/s, and even the official also promises a continuous read speed of up to 300 MB/s and a continuous write speed of up to 250 MB/s.
In addition, the official also shows the memory card in the Blackmagicdesign Disk Speed Test test results, read and write speeds of 252 MB/s, 230 MB/s, respectively, to meet the ProRes 422 HQ under the 2160P50P write and 2160P60P read performance requirements, in the same products is very prominent.
Obviously, SDXC UHS-II V90 512GB is a product for Sony A7S3, A1 users, although its speed is not as fast as the CFxpress Type A card, but the capacity is higher than the latter, and for other users, I am afraid that there is little interest, after all, other high-end mirrorless cameras are generally equipped with CFxpress Type B card slot. ProGrade Digital's new UHS-II SD card offers a total of 64GB, 128GB, 256GB, and 512GB of capacity, with 512GB priced at $460.
