Score: 83/100Rankings
The Angelbird AV PRO SD V90 128 GB is a professional-grade UHS-II SDXC card delivering up to 300 MB/s read and 260 MB/s sustained write speeds. Its rugged build and ECC features add durability but it needs UHS-II hardware and lacks bundled accessories. Best suited for videographers and photographers needing reliable high-speed storage in demanding field conditions.
The ProGrade Digital 512 GB UHS-II SDXC card offers blazing 250 MB/s read speeds and a guaranteed V60 (60 MB/s) sustained write speed, making it ideal for 4K/UHD video and rapid RAW photo bursts. However, its maximum write speed tops out at 130 MB/s and performance falls back to U3/V30 levels in legacy UHS-I slots. It is best suited for professional photographers and videographers who need rugged durability and fast off-loading in UHS-II-compatible devices.

Professional reviewers from Wex Photo Video, B&H Photo Video, and Adorama consistently commend the Angelbird AV PRO SD V90 MK2 for its reliable 260 MB/s sustained write speed, robust durability, and Stable Stream technology that prevents speed drops during long recordings.
Direct consumer reviews are scarce in the available data, but inferred feedback suggests users appreciate the card's fast transfer rates and rugged build for field work.
“The card performs very well for read speeds, with peaks hitting the claimed numbers but occasional drops.”
Professional reviewers praise the card's near-spec read performance and reliable V60 sustained writes, emphasizing its cost-effective speed for 4K and RAW capture. However, they caution that the write speed ceiling and the steep performance loss in legacy UHS-I slots limit its suitability for the most demanding 8K workflows.
Consumer commentary is sparse; the few available mentions echo the professional view, highlighting fast reads and durability but offering no additional praise or complaints.
