SDXC memory cards provide high-capacity, removable storage for compatible digital cameras, camcorders, laptops and other devices, giving you room for high-resolution photos, video recordings and large files. Short for Secure Digital Extended Capacity, the SDXC standard supports capacities greater than 32GB and up to 2TB. That extra space can be especially useful for RAW photography, extended video shoots and keeping more content available without frequently swapping memory cards. Choosing the right SDXC card starts with checking your device’s supported card format and maximum storage capacity. Full-size SDXC cards and smaller microSDXC cards use different physical formats, so make sure the card fits your device’s memory card slot or uses an appropriate adapter. SDXC cards typically use the exFAT file system, which supports individual files larger than 4GB—a helpful feature for lengthy video recordings. Devices designed only for SD or SDHC cards may not support SDXC storage, so confirm compatibility before purchasing. Storage capacity is only part of choosing an SDXC memory card; speed ratings also help you find a suitable option for your workflow. For burst photography and high-resolution video recording, sustained write performance matters because the card needs to keep up as your camera saves data. Speed Class, UHS Speed Class and Video Speed Class markings indicate minimum sequential write speeds under specified conditions. For example, V30, V60 and V90 ratings correspond to minimum sequential write speeds of 30, 60 and 90 megabytes per second, respectively. Your camera’s requirements, including recording bitrate and video settings, should guide your choice rather than resolution alone. Faster advertised read speeds can help shorten file transfers, but actual performance also depends on your device, SD card reader and connection. A compatible UHS-II card reader and host device are needed to take full advantage of UHS-II transfer speeds. Balance capacity, recording requirements and transfer performance to choose SDXC storage that fits your needs, and back up important files to a separate location.

FAQ

SDXC stands for Secure Digital Extended Capacity. An SDXC card is a removable flash memory card used to store photos, videos, audio and other digital files in compatible devices.

SDXC cards are used in compatible digital cameras, camcorders, audio recorders and computers. Look for an SDXC designation in your device’s specifications, since an SD card slot does not automatically support every SD card standard.

SDXC cards typically come formatted with the exFAT file system. The device or operating system accessing the card must support both the SDXC standard and its file system.

Insert the card into an SDXC-compatible card slot or connect an SDXC-compatible card reader to your computer. Once the card appears in File Explorer on Windows or Finder on a Mac, you can browse and copy its files.

For general file storage, use folders labeled by date, project or file type. Cameras and other recording devices may create their own folder structures, so follow the device’s guidance when organizing files directly on the card.
