256GB SDXC card for 4K capture

This SanDisk Extreme SDXC UHS-I card provides 256GB of storage for cameras and devices that accept SDXC media. It targets photographers and videographers who need reliable capacity for high-resolution stills and 4K UHD video recording. The A2 rating also supports faster app loading on compatible devices.

U3 and V30 sustained write performance

The card carries UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings, guaranteeing a minimum sustained write speed of 30MB/s. This specification is the decisive factor for uninterrupted 4K UHD recording at 30 fps. Maximum read speed reaches 230MB/s and maximum write speed reaches 160MB/s.

256GB capacity with 4K UHD headroom

At 256GB the card can hold approximately 719 minutes of 4K UHD video at 30 fps based on a 641MB per minute bitrate. This headroom suits extended shooting sessions without frequent offloads. Users recording at higher bitrates or needing more than 512GB total capacity will need additional or larger cards.

商品問答

What does the 230MB/s read speed mean when the card is inside a camera or card reader?

The 230MB/s read speed is the maximum sequential transfer rate achievable with a compatible UHS-I device; sustained throughput will depend on the host hardware and file sizes.

How does the UHS-I interface affect the 160MB/s write speed claim?

UHS-I provides the bus pathway; the 160MB/s write figure represents peak performance on supported UHS-I hosts under optimal conditions.

What physical slot and device support are required for this 256GB SDXC card?

It requires a full-size SDXC-compatible slot that supports UHS-I; devices limited to SDHC will not recognise the 256GB capacity.
