UHS Speed Class 3 Rated. This UHS Speed Class 3 rating allows capture of uninterrupted, cinema-quality 4K, 3D, and Full HD video at a minimum sustained write speed of 30 MB/s. If you’re shooting 4K video with a camera that uses the SD format, this is what you want.
Fast Read and Write. The 95MB/s read and 90MB/s write speeds allow you to transfer large amounts of data to and from the card with minimal bottleneck. It’s fast enough for most still photography use short of extended continuous shooting. Additionally, accelerated minimum sustained write speeds prevent dropouts and stuttering, making it well-suited for Full HD video recording.
Ultra-High Capacity. At 256GB, this SDXC memory card enables uninterrupted continuous video recording at high data rates.
Error Correction. Sandisk’s Advanced Error Correction Code engine helps to prevent errors that cause potential data corruption.
Known Compatibility Issues. There have been reports of compatibility issues involving memory cards with a speed class of V30 or higher and first generation Blackmagic cameras such as the Blackmagic Pocket Cinema Camera and the Blackmagic Design Micro Cinema Camera.
Please Note. Just because this card is 256GB in size doesn’t mean you should fill it up without a backup. It’s best to not put all of your eggs in one basket!
