SanDisk SDSQXCY-128G-GN6MA 128GB Extreme Pro DJI Mavic Mini MicroSD

The SanDisk Extreme Pro SDSQXCY-128G delivers 200MB/s read and 90MB/s write speeds in a microSDXC form factor rated for Class 10, UHS-I U3, A2, and V30 standards simultaneously. The V30 and U3 ratings guarantee the 30MB/s minimum sustained write floor required by 4K UHD video, but the 90MB/s rated write speed means the card operates with significant headroom above that floor — critical for DJI's variable-bitrate recording modes that can spike well above the V30 baseline. The A2 application performance class adds 4,000 IOPS read and 2,000 IOPS write random performance, addressing the firmware-level random access operations that budget cards handle poorly, resulting in recording errors and corrupted clips.

This bundle targets DJI drone operators specifically, with a verified compatibility list covering Mavic Mini through Phantom 4 and the DJI Smart Controller. The environmental durability ratings — waterproof, temperature-proof, shockproof, X-ray proof — are not marketing language on a card that will live in an aircraft subject to hard landings, moisture, and temperature swings. The included Everything But Stromboli multi-slot card reader is a practical addition that unlocks the card's full 200MB/s read potential for post-shoot transfers, bypassing the drone's UHS-I bus speed limitation. For operators who shoot 4K continuously, 128GB accommodates approximately 35–40 minutes of high-bitrate 4K footage — substantial for most missions, though multi-card workflows are advisable for extended operations.
