High-Speed Performance for Professional Capture

Rated for up to 250 MB/s read speed and up to 130 MB/s write speed, this ProGrade Digital card is optimized for workflows that demand consistent throughput. The V90 classification indicates a minimum sustained write speed of 90 MB/s, making it suitable for high-resolution video formats and data-intensive recording modes where dropped frames are not an option.

Built for Advanced Video Work

The V90 and U3 ratings make this card an excellent choice for professional video creators recording 4K, 6K, and even certain 8K workflows depending on codec and camera requirements. It is especially well-suited to high-bitrate intraframe codecs, All-I recording, and professional hybrid camera applications where stable sustained performance matters more than peak burst numbers alone.

Ideal for Fast Burst Photography

For photographers shooting RAW bursts in sports, wildlife, events, and action-oriented environments, the UHS-II bus and fast write speed help the camera buffer clear more efficiently. This can translate into longer continuous bursts and quicker readiness between sequences on compatible cameras.

64GB Capacity for Flexible Daily Use

The 64GB capacity strikes a practical balance between speed, portability, and media management. It offers enough room for substantial still image sessions and professional video clips while making file organization easier for shooters who prefer separating projects, scenes, or shooting days across multiple cards.

Durable Professional Media

ProGrade Digital memory cards are designed for professional field use, where reliability is essential. Durable construction helps the card withstand the rigors of repeated insertion, travel, location work, and regular production use. For creators who need dependable media in a compact format, this card is built to support demanding real-world shooting conditions.

Workflow Benefits

Fast read speeds can significantly reduce transfer times when offloading content to a computer with a compatible UHS-II card reader. This is valuable for photographers with large RAW sets and videographers handling high-data-rate footage, helping streamline backups, ingestion, and editing preparation.

How It Compares

Compared with standard UHS-I SD cards, a UHS-II V90 card like this offers substantially higher potential performance, especially in compatible devices. It is a stronger choice for advanced codecs, high-frame-rate recording, and burst photography. Compared with larger-capacity cards in the same family, this 64GB version is a smart option for users who want premium speed while keeping individual card capacities more manageable for archive and backup discipline.
