512GB SDXC card for 4K video

The SanDisk Extreme GO SDXC card delivers 512GB of storage for cameras and camcorders that use the SDXC format. It carries UHS-I U3 and V30 speed ratings to sustain high-bitrate 4K UHD recording. The card is built with NAND flash technology rated for temperature, water, shock and magnet resistance. It suits creators who need reliable capture in demanding environments.

230MB/s read and 150MB/s write headroom

Sequential read speeds reach up to 230MB/s for fast offload to a workstation. Write performance tops out at 150MB/s, which covers most 4K workflows but may limit cameras that demand sustained rates above that threshold. The 512GB capacity holds many hours of 4K footage before a card swap is required. Users shooting higher-bitrate formats should verify their device’s minimum write requirement.

Silent solid-state operation

As a solid-state memory card it has no moving parts, produces no audible noise and draws power only from the host device during read or write activity. The ruggedised construction protects data against temperature extremes, water exposure, physical shock and magnetic fields. There are no thermal throttling concerns in normal photographic or video use.

Questions about this item

Will the 512GB SDXC card work in my older camera that only supports SDHC?

The card uses the SDXC standard, which requires a host device with an SDXC slot; SDHC-only devices cannot address the 512GB capacity.

How can I verify the card is delivering its rated U3 V30 performance after formatting?

Run a sustained write test with a tool that reports sequential speed; the card should maintain at least 30MB/s to meet the U3 V30 class for 4K UHD recording.

Does the SDSDXGN-512G-GNCIN include a card reader or adapter in the box?

The product is supplied as the memory card only; a compatible UHS-I card reader or USB adapter must be purchased separately.
