Flashgeheugen SanDisk Extreme PRO 128 GB SDXC UHS-II model SDSDXDM-128G-GN4IN

The SanDisk Extreme PRO 128 GB SDXC UHS-II card offers high sustained performance for capture and transfer of high-resolution photos and video. With up to 300 MB/s read and write speeds and support for UHS Speed Class 3 (U3) and Video Speed Class V90, the card is intended for professional stills shooting and seamless 4K or higher video recording. Durable construction provides resistance to drops and dust, while the 128 GB capacity gives ample space for RAW images, high-bitrate video files and burst shooting sessions.

Advantages

The card combines UHS-II interface performance with high sequential read and write speeds to reduce buffer clearing time and speed up data offload. V90 certification ensures consistent sustained write performance required for high-bitrate 4K/8K video workflows. The compact SDXC form factor remains compatible with cameras and card readers that accept UHS-II SD cards, and the robust exterior helps protect stored data under field conditions.

How to use

Insert the SDXC UHS-II card into a compatible camera slot or a UHS-II-capable card reader. For best write performance during recording, ensure the host device supports UHS-II and the camera firmware is up to date. Format the card in-camera before first use to optimize compatibility with the camera file system. When transferring files, use a UHS-II card reader and USB 3.x or faster host to approach the card's maximum read speeds. Avoid removing the card while the device is writing data.

Recommendations

Store the card in a protective case when not in use, maintain regular backups of important files, and use the card within the camera's recommended temperature and humidity ranges. For continuous high-bitrate recording, verify available capacity and consider swapping to a fresh card before extended takes to avoid running out of space.
