Keep separate cards ready for photography and video workflows with this two card SanDisk Extreme PRO 128GB SDXC UHS I set. The set contains two individual full size 128GB SDXC memory cards, not one 256GB card. Each card is designed for devices that accept full size SDXC cards and support the UHS I interface.

For media transfers, the cards deliver up to 200MB/s read speed with compatible hosts and card readers. Shot speeds are rated up to 140MB/s, supporting sequential burst capture where supported. U3, V30, and Class 10 ratings support compatible 4K UHD recording modes. Actual read, write, and recording performance varies by device, card reader, interface, file type, recording setting, and operating conditions. The up to 200MB/s figure is a read or transfer rating, not a write speed. Before important events or travel, format each card in the intended compatible device and test both cards in your recording workflow.

Maintain copies of important files on separate storage. The cards are described as temperature proof, waterproof, shock proof, and x ray proof under applicable test conditions.
