64 GB SDXC card for high-speed capture
This SanDisk Extreme Pro card offers 64 GB of SDXC storage rated at Class 10 speed. It targets photographers and videographers who need reliable, high-capacity media for continuous shooting. The 170 MB/s read and 90 MB/s write figures support fast buffer clearing and 4K video recording. It is a new accessory built for demanding creative workflows.
UHS-I interface limits sustained throughput
The card operates on the UHS-I bus, which caps real-world transfer rates below the peak 170 MB/s read claim. Write speeds of 90 MB/s are sustainable only while the host device maintains compatible signalling. Older readers or cameras without UHS-I support will fall back to lower speeds. The Class 10 rating guarantees a minimum 10 MB/s sequential write for video.
64 GB capacity suits extended 4K sessions
At 64 GB the card holds hours of 4K footage or thousands of raw images before filling. High-bitrate codecs and long-form recording will consume space faster, requiring offload or a second card. Photographers shooting bursts of large raw files will also reach capacity sooner. It is not suited for multi-day shoots without regular data transfer.

Questions about this item
Should I choose the 64 GB version or a different capacity?
This listing is for the 64 GB SDXC card; other capacities are separate products not described here.
What does the 170 MB/s read figure mean when the card is in my camera?
The 170 MB/s read speed is the maximum sequential rate the card can deliver; sustained performance depends on your camera's write pipeline and buffer.
Does the Class 10 rating limit the 90 MB/s write speed in practice?
Class 10 guarantees a minimum of 10 MB/s sustained write; the card can reach up to 90 MB/s write when the host device supports the required bus mode.
