512GB SDXC card for everyday cameras

The SanDisk Ultra SDXC UHS-I card delivers 512GB of storage for compact and mid-range point-and-shoot cameras. Its Class 10 and U1 ratings guarantee the sustained write performance needed for Full HD 1080p video recording. Photographers who need reliable capacity for long shooting sessions will find this card a practical fit.

Silent solid-state operation with low power draw

As a flash memory device, the card has no moving parts, producing zero acoustic noise during read or write cycles. Power consumption remains minimal, drawing only what the host device supplies through the SD slot. This keeps battery drain low during extended photo or video capture.

Full-size SD form factor for direct device insertion

The card uses the standard full-size SD form factor, slotting directly into compatible cameras, laptops or card readers without adapters. Quick read speeds up to 150MB/s accelerate file offloads to a computer when paired with a UHS-I reader. Buyers who need smaller microSD media or faster UHS-II throughput should look elsewhere.

Questions about this item

How do I install the SanDisk SDSDUNC-512G-GN6IN into my camera, and what step do people often get wrong?

Insert the full-size SD card label-side up until it clicks; the common mistake is forcing it in upside-down, which can damage the 512GB card's contacts.

What maintenance or replacement will this SanDisk Ultra SDXC card need over time?

No scheduled maintenance is required; replace the card if write errors appear or after heavy Full HD 1080p video use depletes its write-cycle endurance.

What limit appears first during sustained Full HD video recording on this UHS-I U1 card?

The Class 10 / U1 rating guarantees a minimum 10MB/s write speed, so sustained 1080p recording is the first limit you will reach before the 150MB/s read ceiling.
