  • Write up to 299 MB/s for reliable 4K capture

Built for Extreme Capture

The Sony 64GB UHS-II Tough SDXC card delivers read speeds up to 300 MB/s and write speeds up to 299 MB/s. It is engineered for professionals who require reliable high-resolution 4K video recording in harsh environments where standard cards might fail.

Simple Slot Installation

Installation is straightforward: insert the card into a compatible UHS-II SD slot. The ribless, one-piece moulded construction removes the write-protect switch and ribs found on conventional cards, eliminating the common failure points of broken tabs or jammed mechanisms that cause recording errors.

UHS-II Bus Limits

The card operates on the UHS-II interface, so sustained throughput depends on the host device supporting that bus. In UHS-I slots, speeds fall back to the lower specification. The IP68 rating certifies survival in 16 feet of water for 72 hours and 18-times standard bend resistance, but does not guarantee operation while submerged.

Questions about this item

How can I confirm the card is delivering the rated 300 MB/s read and 299 MB/s write speeds after installation?

Use the supplied SD Scan Utility to run a full health and speed test; it reports actual throughput and flags any blocks that fall below the 300/299 MB/s targets.

What does the package contain and is a reader included?

The box holds the 64 GB UHS-II TOUGH SDXC card only; a compatible UHS-II card reader must be purchased separately to reach the quoted speeds.

Which capacity should I choose for extended 4K sessions — the 64 GB version or a larger one?

At 64 GB you can record roughly two hours of 4K footage; if you need longer continuous shoots, select a higher-capacity SF-G TOUGH card instead.
