Know before you buy
Yes, this card is backward compatible with UHS-I devices. However, you will be limited to the maximum speed supported by your camera's card slot rather than the card's full potential.
To achieve the maximum transfer speeds, you should use a compatible UHS-II SD card reader, such as the SanDisk PRO-READER. Standard UHS-I readers will significantly throttle your transfer times.
Yes, it is rated V30, which guarantees a minimum sustained write speed of 30MB/s. This is sufficient for recording smooth, stutter-free 4K UHD video.
QuickFlow is a proprietary technology designed to optimize offloading speeds. When paired with a compatible reader, it allows you to move large files from your card to your computer much faster than standard cards.
Absolutely. The card is optimized for sequential burst mode, meaning it can handle the rapid data stream generated when you take multiple high-resolution photos in quick succession.
