Choosing an SD card for a camera and video workflow
Match card type, sustained write speed and capacity to your camera’s actual recording requirements.
Check your camera’s supported formats
SD, microSD, SDHC and SDXC have different compatibility requirements. Check the official manual for supported capacities and card types, rather than assuming every card fits an adapter and works.
Sustained write speed is key
A headline maximum read speed is not the same as sustained video recording speed. Compare the camera’s required video speed class and bitrate with the card’s stated minimum sustained performance.
Plan for offloading and duplicates
Large cards mean fewer swaps but can hold a lot of irreplaceable footage if lost. If your workflow permits, transfer and back up content after each recording session rather than waiting until a card fills.
Before you order
Choose an established seller and check authenticity and warranty. Avoid relying on unknown, unusually cheap cards for important projects, and test a new card with the camera before a paid shoot.
Use the product manufacturer’s current specifications and the retailer’s return terms to verify fit and compatibility before purchase. This guide explains selection criteria; it is not a hands-on review of any specific product.
