SanDisk Extreme 256GB SDXC UHS-I U3 V30 180MB/s Memory Card (SDSDXVV-256G-GNCIN)

256GB SDXC card for 4K video

This 256GB SanDisk Extreme SDXC card is built for photographers and videographers who need reliable capture of 4K UHD footage and sequential burst images. It carries UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings to sustain continuous recording without dropped frames. Read speeds reach 180MB/s to accelerate offload workflows.

Upgrade from slower Class 10 or U1 cards

Moving up from a basic Class 10 or U1 card removes the bottleneck that causes recording stops or slow buffer clearing during burst shooting. The jump is worth it when your camera writes 4K UHD (3840 x 2160) or Full HD (1920x1080) video at high bitrates, or when you shoot long RAW bursts that exceed the write ceiling of older media. Cards without V30 cannot guarantee the sustained throughput those modes demand.

Fits standard SDXC slots and UHS-I readers

The card slots into any host device that supports the SDXC format and UHS-I bus. Pairing it with a SanDisk Professional PRO-READER SD and microSD enables the quoted 180MB/s offload rate, while other UHS-I readers will operate at their own maximum. It requires no extra power or adapters beyond the slot itself, freeing you from carrying proprietary media or bulky external recorders for the same capacity.
