OVERVIEW
High-Performance Professional Storage
The ProGrade Digital 256GB SDXC UHS-II V90 Memory Card is engineered for photographers, videographers, and hybrid creators who need dependable speed for modern high-resolution capture. With a fast UHS-II bus design and V90 video speed rating, this card is built to keep up with high-bitrate video, rapid burst shooting, and large file transfers in demanding production environments.
Designed for Advanced Video Capture
This card is especially well suited for professional video applications where sustained write performance matters. The V90 classification indicates a minimum sustained write speed of 90 MB/s, making it appropriate for demanding codecs, high frame rates, and high-resolution recording modes used in many mirrorless cameras, camcorders, and cinema-oriented devices that support SDXC media. Whether you are shooting 4K, 6K, or certain 8K workflows depending on your camera's requirements, the card is designed to provide stable recording performance.
Fast Read and Write Speeds
Rated for up to 300 MB/s read speed and up to 250 MB/s write speed, the ProGrade Digital 256GB SDXC UHS-II V90 card helps reduce downtime both in-camera and at the workstation. Fast write speeds help maintain responsiveness during continuous shooting, while high read speeds accelerate offloading to a compatible UHS-II card reader. This can be a major advantage for event shooters, sports photographers, wedding professionals, and video editors working on tight deadlines.
Built for Burst Photography
For still photographers, speed is not just about transfer times. A fast UHS-II V90 card can help cameras clear their internal buffers more efficiently after long continuous bursts. This makes the card a strong match for wildlife, action, sports, and photojournalism applications where missing a decisive moment is not an option. The 256GB capacity also gives you room for large RAW files, long burst sequences, and extensive full-day shoots.
256GB Capacity for Serious Creators
With 256GB of storage, this SDXC card provides a practical balance of high capacity and workflow flexibility. It can accommodate thousands of JPEGs, substantial RAW image sets, and extended video sessions depending on resolution, bitrate, and codec. Many creators prefer 256GB cards because they offer enough capacity for demanding assignments while still being easy to organize across multiple shoots or camera bodies.
UHS-II Advantage
The UHS-II interface uses an additional row of contacts to enable substantially faster communication than standard UHS-I cards when used in compatible devices. In a UHS-II compatible camera or reader, you can take full advantage of the card's speed potential. The card also remains broadly compatible with SDXC-capable devices that support SD cards, though performance will depend on the host device and whether it supports UHS-II operation.
Professional Reliability
ProGrade Digital has built a strong reputation among image makers for focusing on performance, consistency, and professional workflow needs. This card is intended for repeated, everyday use in real production environments, including frequent insertion and removal from camera bodies and readers. For creators who depend on media performance during paid assignments, reliability is just as important as headline speed, and this card is designed with that expectation in mind.
Who It's For
This memory card is ideal for advanced enthusiasts and professionals using mirrorless cameras, DSLRs, broadcast devices, audio/video recorders, and other compatible hardware that can benefit from SDXC UHS-II media. It is particularly appealing for users who shoot large RAW stills, high-frame-rate bursts, 10-bit video, or high-bitrate intra-frame codecs that demand strong sustained write performance.
How It Compares
Compared with standard SD cards or slower UHS-I media, a UHS-II V90 card offers substantially higher performance for both recording and transfer. Compared with lower-rated V30 or V60 cards, this V90 model is a better choice for more demanding professional video modes and for users who want additional performance headroom. While some workflows may move to CFexpress or other media formats for extreme data rates, SDXC UHS-II V90 remains a highly versatile and widely supported format for many professional cameras.
Usage Tips
For best results, use this card in a camera and card reader that explicitly support SDXC UHS-II media. Format the card in-camera before important shoots, avoid filling it completely when recording critical long-form video, and use a fast UHS-II reader to maximize transfer performance. It is also good practice to rotate multiple cards on professional assignments and maintain redundant backups of your footage and image files as soon as possible after capture.
Recommended Accessories
To get the most from this memory card, pair it with a dedicated ProGrade Digital or other high-quality UHS-II SD card reader for rapid ingest. Protective memory card cases are useful for travel and field work, especially when carrying multiple cards. If you routinely record high-bitrate video, consider adding additional matching SDXC UHS-II V90 cards to maintain a consistent workflow across multiple cameras or extended shoots.
