SanDisk Extreme PRO UHS-II Cards UHS-II 256GB SD - 300MB/s(R) - 250MB/s(W) - SDSDXEM-256G-GN4IN

The SanDisk Extreme PRO UHS-II 256GB SDXC card is a high-speed memory card with read speeds up to 300MB/s and write speeds up to 250MB/s, suited to photographers and other creators who need fast file transfers and a large-capacity SD card.

Recommended For

• Photographers using a UHS-II camera for RAW bursts who want the card to clear the camera buffer faster between sequences.
• Video creators whose camera supports SD UHS-II and calls for V60 media, including compatible 4K or 6K recording modes.
• Photographers and videographers who regularly move large files to a computer and can use a UHS-II reader to take advantage of faster transfers.
• Mirrorless or DSLR shooters who want one 256GB SDXC card for extended shoots, while their camera supports SDXC and UHS-II.

Real-World Use Scenarios

• When shooting RAW bursts of wildlife, sports, or other fast action in a UHS-II camera, the card can help the camera clear its buffer between bursts; the camera’s own buffer and card-slot performance still limit how long you can shoot continuously.
• For video shoots in a camera that supports the required SD card class, its V60 rating supports recording modes requiring up to 60 MB/s sustained writing, including some 4K and 6K workflows; confirm the camera’s requirements for the specific resolution, frame rate, and codec.
• For a full day of photography or video, the 256GB capacity gives users room for a substantial batch of files before swapping cards, though the amount it holds varies with image size, recording settings, and file format.
• After a shoot, importing large photo and video files through a UHS-II card reader can make offloading more convenient than using a slower card and reader; actual transfer time depends on the reader, computer, and files, and may not reach the card’s advertised maximum speed.
