Ready for compact cameras

The SanDisk SDSDUN4-512G-GN6IN is a 512GB SDXC card built for compact to mid-range point-and-shoot cameras. It carries UHS-I, U1 and Class 10 ratings for reliable Full HD 1080p video capture. The 512GB capacity stores thousands of photos and long video clips without frequent swaps.

Works with UHS-I readers

The card plugs into any SDXC slot and reaches its 120MB/s read ceiling when paired with a UHS-I card reader. No extra power or drivers are required, so the host device stays simple. Write performance meets the U1 minimum, freeing the camera buffer for continuous shooting.

Steady throughput for long takes

Sustained write speeds satisfy the U1 and Class 10 guarantees, preventing frame drops during extended 1080p recording sessions. The controller manages wear across the full 512GB, keeping performance consistent from the first shot to the last. Heat stays low in the small form factor during prolonged use.

Questions about this item

How long can the 120MB/s read speed be sustained before it drops?

The 120MB/s figure is a peak read speed; sustained throughput depends on the host device and file sizes, so the card does not publish a sustained-rate limit.

Does the card run hot or draw extra power during all-day Full HD recording?

The card is rated UHS-I U1 and Class 10 for 1080p video; it operates within standard SDXC power limits and produces no noticeable heat in typical camera use.

Which card reader do I need to reach the 120MB/s transfer rate?

A SanDisk SD UHS-I card reader (sold separately) is required to achieve the quoted 120MB/s transfer speeds.
