Fast and Reliable Memory Cards 

Review by Gilmar Smith

We photographers and videographers can agree on something when it comes to memory cards: our priorities are speed and reliability. And that’s exactly what ProGrade Digital cards are all about. 

ProGrade Digital is a small company created by industry veterans with previous experience at Lexar and SanDisk. Their focus is on building professional-grade, high-quality products with stable worldwide prices that are a good value to the consumer. 

The SDXC UHS-II, U3, Class 10, V90 memory card is guaranteed to perform at a maximum read rate of 250 MB/s and a write speed of 200 MB/s, with a guaranteed minimum writing speed of 90 MB/s. Its speed makes it suitable for continuous-burst mode—perfect for sports photographers. The ProGrade Digital V90 features precise capture when recording 6K, 4K, full-HD, and 3D video, as well as high bit rate MPEG-4 files. 

The cards are designed to withstand extreme operating temperatures from –13ºF to +185ºF and storage temperatures from –40ºF to 185ºF. 

They also come with a built-in, write-protect switch that prevents accidental data loss (talk about a lifesaver!). They’re shockproof, X-ray-proof, and come with a three-year warranty. 

The ProGrade Digital SDXC UHS-II, U3, Class 10, V90 memory cards are compatible with Canon, Sony, Nikon, Olympus, Panasonic, Fuji, and Samsung cameras and are available in the following capacities: 64 GB, 128 GB, and 256 GB. ■
