SanDisk SDSQXCY-128G 128GB Extreme Pro DJI Drone MicroSD Card

The SanDisk Extreme Pro 128GB microSDXC card is rated at 200MB/s read and 90MB/s write, with V30, U3, and A2 speed class certifications. In the context of drone video recording, the V30 certification is the critical specification: it guarantees a sustained minimum write speed of 30MB/s, which is the threshold required by 4K UHD recording at the bitrates used by DJI Mavic and Phantom series drones. The A2 class rating adds 4,000/2,000 IOPS (read/write) random performance, which addresses the file system overhead of managing large video files — a factor that causes lower-class cards to stall even when sequential write speed appears adequate. The 200MB/s read speed is a post-session transfer specification, not an in-flight recording figure, but it is directly relevant to workflow efficiency: at that throughput, 128GB of footage can be offloaded in under 11 minutes on a compatible reader.

This card is built specifically for the environmental and performance demands of drone operation. The four-proof certification (temperature, waterproof, shockproof, X-ray) covers the real failure modes of field use — cold temperatures at altitude, wet landings, and mechanical shock during crashes. The confirmed compatibility list covers the core DJI Mavic and Phantom product lines, making this a low-risk specification choice for DJI users who need a card that won't require per-drone research. The included Everything But Stromboli multi-slot reader provides immediate transfer capability across four card formats, though users seeking maximum transfer speeds should note that the reader's USB interface speed, not the card's rated read speed, will be the bottleneck. At 128GB, this card is sized for single-session 4K shoots; operators doing multi-hour productions should plan for either a second card or mid-session offload.
