ProGrade Digital 512GB SDXC UHS-II V90 Memory Card

The ProGrade Digital 512GB SDXC UHS-II V90 Memory Card is a professional-grade storage solution designed for photographers, filmmakers, and content creators who need speed, capacity, and dependable performance. With a large 512GB capacity, SDXC format, and UHS-II interface, this card is well suited for workflows involving high-resolution stills, RAW image sequences, and advanced video formats including high-bitrate 4K, 6K, and even 8K recording on compatible cameras.

Compatible With

• DSLR, mirrorless, and cinema cameras with SDXC UHS-II or SDXC UHS-I card slots
• Professional camcorders and video recorders that accept full-size SDXC media
• UHS-II SD card readers and dual-slot readers supporting SDXC cards

Built for Professional Video Capture

The V90 video speed class is one of the key highlights of this card. A V90 rating indicates a minimum sustained write speed designed for demanding video applications, making it an excellent fit for professional recording modes that generate large data streams. This helps reduce the risk of dropped frames or interrupted recording when using supported cameras that shoot in high-bitrate codecs, All-I formats, or high-resolution video modes.

Fast Read and Write Performance

With maximum read speeds up to 300 MB/s and maximum write speeds up to 250 MB/s, this ProGrade Digital card is built to keep pace with modern imaging demands. Fast write speeds are particularly useful for clearing camera buffers during continuous burst photography, while fast read speeds help accelerate transfers to a computer for editing, backup, and delivery. For working professionals, these time savings add up significantly across large shoots and repeated ingest sessions.

High Capacity for Long Shoots

The 512GB capacity gives creators the flexibility to shoot longer sessions without changing cards as often. This is especially beneficial for weddings, sports, documentary production, interviews, event coverage, travel assignments, and extended studio sessions. Large capacities are also valuable when shooting RAW photo sequences, 10-bit or 12-bit video, and other data-heavy formats that quickly consume storage space.

Designed for Hybrid Creators

Today's hybrid shooters often move between still photography and video capture in the same assignment. This card is designed to support both types of work. Photographers benefit from rapid burst handling and fast file transfers, while videographers gain the sustained write performance necessary for demanding recording modes. That versatility makes it a strong choice for creator kits centered around modern mirrorless and professional video-capable cameras.

UHS-II Advantage

The UHS-II bus interface uses an additional row of contacts to enable faster data transfer than standard UHS-I cards when used in compatible devices. In a UHS-II camera or card reader, this can deliver significantly improved performance. The card may also work in many UHS-I compatible devices, though performance in those systems will be limited by the host device's interface speed.

Reliable Option for Professional Workflows

ProGrade Digital has built a strong reputation around professional memory and workflow products intended for demanding production use. Cards in this class are commonly selected by users who need predictable performance on paid assignments, where media reliability and data throughput matter as much as raw capacity. For critical projects, many professionals pair cards like this with disciplined backup practices and verified card readers to maintain a secure workflow from capture to archive.

How It Compares

Compared with basic SD cards or UHS-I models, a UHS-II V90 card offers a clear performance advantage for advanced capture modes. Slower cards may be sufficient for casual photography or lower-bitrate video, but they can become a bottleneck during long bursts, professional codec recording, or high-resolution production. Compared with lower-capacity cards, the 512GB size reduces card swaps and streamlines shoot management. For creators working in fast-paced environments, that can make a meaningful difference in efficiency.

Usage Tips

For best results, use this card in a camera and card reader that both support SDXC UHS-II media. Format the card in-camera before important shoots, and avoid mixing heavily fragmented data from multiple devices without reformatting as needed. If your camera features dual card slots, confirm whether both slots support UHS-II speeds, since some cameras provide full speed on only one slot. Offloading through a quality UHS-II reader will help you realize the card's top transfer performance.

Recommended Accessories

To get the most from this memory card, consider pairing it with a dedicated UHS-II SD card reader for faster transfers, a rugged storage drive for backup, a protective memory card case for travel and field work, and a second matching card for redundant recording or overflow capture in compatible dual-slot cameras. These accessories help create a faster, safer, and more efficient end-to-end workflow.
