Buying Guide
What does UHS-I mean for performance?
UHS-I is a standard that affects read and write speeds, impacting transfer times and handling of high-bitrate media. Cards labeled UHS-I that support fast transfer speeds can reduce offload time and improve timeliness in workflows.
How to choose by capacity?
Higher capacities reduce the need to swap cards but come at a price. For 4K video and rapid shooting, 128GB–256GB is common for professionals, while 64GB–128GB suits everyday photography and casual use. Always match capacity to your typical file size and shooting frequency.
What about speed class and video speed class?
Look for C10, U3, and V30 designations as indicators of minimum sustained write speeds, especially for 4K video. SanDisk QuickFlow Technology can further boost offload performance on supported capacities and devices.
