SanDisk 1TB_TF_Extreme Pro_R4 Extreme MicroSD Card DJI Mavic Mini 2

The SanDisk Extreme 1TB microSD card delivers sequential read speeds of up to 160MB/s and write speeds of up to 90MB/s, with UHS Speed Class 3 (U3), Video Speed Class 30 (V30), and Application Performance Class A2 ratings. In practical terms: V30 guarantees the sustained 30MB/s minimum write floor required for 4K UHD video recording, while A2 means random read/write IOPS meet a defined minimum that accelerates small-file access patterns. The 1TB capacity is the headline specification — it's approximately four times the largest microSD cards that were widely available just a few years ago, enabling multi-hour 4K recording sessions, large RAW photo bursts, and app storage without mid-session swaps. The four-element durability certification (temperature-proof, waterproof, shockproof, X-ray proof) is a hardware-level assurance that the card survives the field conditions drone and action camera shooters regularly encounter.

This card is positioned for drone operators, action camera users, Android power users, and hybrid smartphone shooters who generate high volumes of high-bitrate content and need the storage to keep pace with their capture rate. The DJI Mavic Mini 2 is the featured compatibility reference, but V30/A2-rated microSD cards are appropriate for any device that supports them — GoPro action cameras, Samsung and Pixel flagship smartphones, and Nintendo Switch gaming all benefit from this speed tier. The included multi-slot card reader (SD, microSD, M2, MS) and SD adapter make the bundle a complete transfer solution out of the box. The USB-A reader is the one legacy element in an otherwise current-spec package — USB-C laptop users will need a separate adapter or hub to use it directly.
