Running out of card mid-shoot is an avoidable problem, and 256GB is the size that makes it stop being a consideration on a full day of 4K.
This is a SanDisk Extreme PRO rated V30, U3 and Class 10, which guarantees the sustained write speed that 4K video needs — the specification that actually matters, as opposed to the headline read speed. It handles up to 200 MB/s read and 140 MB/s write, so offloading at the end of the day is quick too. A built-in write-protect switch guards against wiping the card by accident before the footage is backed up.
Rented for 4K video, raw and burst photography, and multi-day shoots. The 128GB version is available if you need less.
