64GB SDXC Card for 4K Video

The SanDisk Extreme Pro SDXC card delivers 64GB of storage in the full-size Secure Digital form factor. It meets the UHS-I interface with U3 and V30 ratings, sustaining a minimum write speed of 30MB/s for uninterrupted 4K recording. Read speeds reach up to 95MB/s and write speeds up to 90MB/s for rapid file offload. The card carries a Class 10 speed rating and a 633x multiplier for broad device compatibility.

Suited to Cameras and Camcorders

This card suits photographers and videographers capturing 4K footage or high-resolution burst sequences on UHS-I cameras, drones or camcorders. The mechanical write-protect switch adds a physical safeguard against accidental erasure. Users needing capacities beyond 64GB or the higher sustained throughput of UHS-II or UHS-III interfaces should consider other options. Devices limited to SDHC formatting will not recognise this SDXC card.

Sustained Write Performance

Under continuous recording loads the V30 rating guarantees a 30MB/s floor so frame drops do not appear during long takes. Peak write bursts can touch 90MB/s while the controller manages thermal limits and wear levelling across the 64GB array. Read operations maintain up to 95MB/s for efficient post-production ingest. The solid-state construction has no moving parts, preserving battery life in portable gear during extended sessions.

Questions about this item

What host device slot is required for the 64GB SDXC card to work?

The card needs a full-size SDXC-compatible slot; older SDHC-only readers will not recognise the 64GB capacity.

Does the UHS-I U3 V30 card fall back to Class 10 speeds in a legacy SDHC reader?

Yes, it will operate at the Class 10 10MB/s minimum write speed when the host does not support UHS-I.

How can I confirm the card is delivering its rated 95MB/s read and 90MB/s write after setup?

Run a benchmark tool such as CrystalDiskMark or Blackmagic Disk Speed Test on a UHS-I host and verify sequential results reach the rated figures.
