Product identity

The SanDisk Extreme Pro SDXC card delivers 256GB of storage for cameras and mobile devices that use the SD form factor. It carries UHS-I, U3, V30 and A2 ratings, making it suitable for 4K UHD video and high-resolution stills. Read speeds reach 250MB/s and write speeds reach 170MB/s.

Upgrade path

This card replaces slower SDHC or lower-class SDXC media that cannot sustain 4K UHD recording or fast burst shooting. The jump is worth it when your current card limits video bit-rates or forces long buffer clears between bursts.

Capacity and headroom

At 256GB the card holds roughly 2,808 minutes of 4K UHD footage at 30 fps, based on a 641MB per minute rate. It handles extended 4K sessions and large RAW libraries, but prolonged 8K or high-frame-rate 4K workflows will exhaust the space.

Questions about this item

Does the SDXC form factor fit a standard full-size SD slot?

Yes, the card uses the standard SDXC form factor so it fits any full-size SD slot that supports SDXC capacity.

What is the correct way to insert the card so the UHS-I interface is active?

Align the label side up, push the card straight in until it clicks, and do not force it at an angle or the UHS-I pins may not seat.

How often should the 256 GB card be reformatted to maintain A2 performance?

Reformat in the camera or device after each major shoot, or at least once a month, to keep the A2 application performance consistent.
