SanDisk SDSQXCD-128G 128GB Extreme Pro MicroSD Card DJI

The SanDisk Extreme Pro SDSQXCD-128G is a 128GB microSDXC card rated at up to 200MB/s sequential read and 90MB/s sequential write, with UHS-I interface operating on the UHS Speed Class 3 (U3) bus and Video Speed Class 30 (V30) certification. In practical terms, the 200MB/s read ceiling means a fully loaded 128GB card empties to a USB 3.0-connected computer in under 11 minutes under ideal conditions — a meaningful improvement over older 160MB/s-class cards. The V30 rating is the key spec for video work: it establishes a contractual 30MB/s minimum write floor, which is the threshold at which most 4K UHD drone cameras stop experiencing buffer-induced recording interruptions. The A2 application class designation adds 4,000/2,000 IOPS random read/write performance, indicating a controller tuned for mixed workloads rather than purely sequential transfers.

This card is built explicitly for DJI drones — the listing calls out Mavic Mini, Mavic 2 Pro/Zoom, Spark, Phantom 3, and Phantom 4 — and the spec set aligns tightly with what those platforms demand. It also translates well to action cameras recording 4K or high-frame-rate 1080p. The bundle with a USB 3.0 reader makes it a ready-to-fly package for pilots who need to start offloading footage immediately. For studio supply contexts, this card is positioned as a prosumer storage solution for content creators working in field environments where reliability and speed matter more than absolute cutting-edge specs.
