ProGrade Digital Introduces New $500 UHS-II V90 512GB SD Card

ProGrade Digital has announced a new 512GB UHS-II V90 Series SD Card that will never drop below a steady write speed of 90MB/s. The company says it is one of the first to offer and ship a card capable of achieving these sustainable write speeds at this capacity.

Formed by industry experts at Lexar and SanDisk, ProGrade Digital is among those that camera companies like Canon and Nikon regularly recommend thanks to its clear performance at the highest levels.

The company says the high-capacity 512GB SDXC UHS-II V90 memory card falls into the Cobalt media class, meaning it promises sustainable read speeds of up to 300MB/s and stable write speeds of up to 250MB/s, but write speeds won’t drop to Less than 90MB/s at any time through card capacity.

This is the case with these cards as well, although ProGrade says its Cobalt-class cards are designed for high-end video workflow that requires higher steady write speeds to prevent dropped frames.
