Built for high-resolution capture

The SanDisk Extreme Pro 64GB SDXC card targets photographers and videographers who need reliable UHS-I performance. It carries U3, V30 and Class 10 ratings that guarantee sustained write speeds for 4K UHD recording. The 64GB capacity suits extended shooting sessions without frequent card swaps. QuickFlow technology streamlines offloading when paired with a compatible reader.

64GB capacity and UHS-I speed limits

Rated read speeds reach 200MB/s while shot speeds hit 140MB/s for burst photography. Sustained write performance is rated at 90MB/s, meeting the V30 minimum for continuous 4K video. The card handles high-bitrate formats and rapid RAW bursts comfortably. Workflows demanding faster sustained throughput or larger single-card volumes will exceed this UHS-I ceiling.

UHS-I slot compatibility and workflow speed

The card fits any SDXC or UHS-I host device, from mirrorless cameras to drones and recorders. Maximum transfer rates require the SanDisk Professional PRO-READER SD and microSD, sold separately. Without that reader, offload speeds fall back to the host slot capability. The design withstands water, shock and temperature extremes for field reliability.

Questions about this item

Will the 64GB SDXC card work in my older camera that only supports SDHC?

The card is SDXC format and requires a host device that supports SDXC; SDHC-only devices cannot address the 64GB capacity.

How can I verify the 200MB/s read speed after setup?

Use the SanDisk Professional PRO-READER SD and microSD with a USB 3.0 or faster port and run a benchmark tool to confirm transfer rates up to 200MB/s.

What comes in the box and do I need to buy a reader separately?

The box contains the 64GB Extreme Pro SDXC card; the SanDisk Professional PRO-READER for maximum 200MB/s transfers is sold separately.
