SANDISK Extreme PRO SD UHS-II V90 Card - 256GB

The SanDisk Extreme PRO SD UHS-II V90 Card - 256GB is a high-performance SDXC memory card designed for professional creators who need speed, reliability, and sustained recording performance. With a UHS-II interface, V90 video speed class rating, and large 256GB capacity, this card is engineered to support demanding workflows such as high-resolution still photography, continuous burst capture, and high-bitrate video recording. It is an excellent choice for photographers, filmmakers, content creators, and hybrid shooters using compatible UHS-II SD devices.

Compatible With

• SDXC-compatible cameras, camcorders, and recorders with SD card slots
• UHS-II compatible mirrorless cameras and DSLRs from brands such as Canon, Nikon, Sony, Fujifilm, Panasonic, and OM System
• Professional video devices that support SDXC UHS-II V90 media
• Also works in UHS-I and standard SDXC devices at the host device's supported speed

Built for High-End Capture

This card is tailored for serious imaging applications where performance consistency matters. The V90 classification indicates a minimum sustained video write speed of 90MB/s, making it suitable for advanced recording formats including 8K, 6K, 4K, All-Intra, RAW, and other data-intensive codecs used by modern cameras. Photographers shooting long bursts of RAW stills will also benefit from the card's fast write capability, which helps reduce buffer-clearing times and keeps the camera ready for the next sequence.

Fast Read and Write Speeds

With maximum read speeds up to 300MB/s and maximum write speeds up to 260MB/s, the SanDisk Extreme PRO SD UHS-II V90 256GB card helps streamline both capture and post-production. Fast read performance shortens file transfer times when offloading large photo libraries or video clips to a computer, while robust write speeds support uninterrupted recording and rapid image capture in the field. For professionals on deadline, faster transfers can make a meaningful difference in workflow efficiency.

256GB Capacity for Extended Sessions

The 256GB capacity offers an effective balance between high storage volume and practical media management. It provides room for extensive still photo sessions, long-form video clips, event coverage, interviews, documentary work, and travel productions without constant card swaps. This makes it especially useful for creators who want fewer interruptions during important shoots.

Professional Reliability and Durability

SanDisk's Extreme PRO line has long been associated with professional-grade performance, and this card is built to operate in demanding environments. It is designed to withstand common field hazards such as shock, water exposure, temperature fluctuations, and airport X-rays. That durability makes it a dependable option for studio use, outdoor production, destination work, sports, wildlife, documentary shooting, and travel assignments where gear may be exposed to changing conditions.

UHS-II Performance with Backward Compatibility

The card uses the UHS-II bus interface, recognizable by its extra row of contacts, to deliver much higher potential throughput than standard UHS-I media when used in compatible devices and card readers. It also remains backward compatible with SDXC and certain UHS-I devices, though performance will be limited to the host system's supported standard. For best results, pair it with a UHS-II camera and UHS-II card reader.

Who It Is For

This memory card is well suited to professional wedding photographers, sports shooters, commercial still photographers, cinematographers, documentary crews, and hybrid creators who routinely work with large files. If your workflow involves RAW image capture, 10-bit or higher video recording, high frame rates, or longer takes, this card is designed to help keep pace with your equipment.

How It Compares

Compared with standard SD cards or lower-rated UHS-I media, the SanDisk Extreme PRO UHS-II V90 card offers much faster transfer rates and more dependable sustained write performance. Compared with V30 or V60 cards, a V90 card is better suited to the most data-heavy recording modes and more demanding professional capture scenarios. For users of advanced mirrorless and cinema-oriented cameras that can take advantage of UHS-II media, this card represents a meaningful upgrade in both speed and workflow confidence.

Usage Tips

To maximize performance, format the card in-camera before important shoots, use a quality UHS-II compatible card reader for transfers, and avoid removing the card while the camera's write light is active. Keeping multiple cards organized in a protective card case can also improve reliability on set. For mission-critical recording, many professionals rotate cards regularly and back up footage immediately after capture.

Recommended Accessories

For the best experience, consider pairing this card with a UHS-II SD card reader, a durable memory card wallet or hard case, and a reliable backup drive or SSD for fast offloads in the studio or on location. Cameras with dual SD slots can also benefit from using matched UHS-II cards for relay, backup, or simultaneous recording workflows.
