The Sony A6400 is a powerful mirrorless camera known for its impressive autofocus system, 4K video recording, and excellent image quality. To fully utilize these capabilities, selecting the right SD card is crucial. The A6400 supports SDHC, SDXC, and UHS-I memory cards. While UHS-II cards can be used, the camera cannot fully leverage their increased speed.

Read and Write Speeds: Write speed affects how quickly the camera saves images and videos. Look for cards with write speeds of at least 70 MB/s for efficient performance.
Storage Capacity
32GB to 64GB: Suitable for casual photographers who shoot mainly in JPEG.
128GB: Ideal for enthusiasts capturing RAW photos and extended video sessions.
256GB and Higher: Best for professionals who record long 4K videos or engage in high-volume shooting.
