What memory card should I use for my DJI drone?
I just got a DJI Mini 4 Pro and need to buy a microSD card. I see cards with different ratings like V30, A2, UHS-I, and UHS-II. What speed class do I actually need for 4K video and what size should I get?

For the DJI Mini 4 Pro and Air 3 recording 4K video, you need a microSD card rated at minimum A2 V30 UHS-I with at least 100 MB/s write speed. The SanDisk Extreme (around $15 to $20 for 128GB) and SanDisk Extreme Pro are the most widely used and proven reliable choices among DJI pilots. The Samsung PRO Endurance is another excellent option, especially if you plan to do a high volume of recording over the drone's lifetime.
Avoid cheap generic cards even if they claim sufficient speed ratings. Card failures during recording result in corrupted footage and lost shots with no recovery option. The price difference between a quality card and a generic one is $10 to $15. That $10 savings is not worth the risk of losing irreplaceable footage. Buy a 128GB card from a known brand and keep a second one as a spare for extended shoots.

Speed class decoded: V30 means a minimum sustained write speed of 30 MB/s, sufficient for most 4K recording. A2 means the card is optimized for random read/write access, which helps with faster file access. UHS-I is the bus interface speed. For standard 4K/30fps and 4K/60fps recording on a DJI Mini 4 Pro or Air 3, V30 A2 UHS-I cards with 100 MB/s read speed are the practical sweet spot.
For the highest recording modes like 4K/100fps or D-Log M at maximum bitrate, UHS-II or V60 rated cards provide extra write speed headroom and reduce the chance of frame drops or recording stops. If you stick to standard 4K recording and do not push the maximum bitrate settings, a good V30 card handles everything the Mini 4 Pro can throw at it without issue.

Capacity planning: 64GB holds roughly 1.5 to 2 hours of 4K video at DJI's standard bitrates. 128GB holds 3 to 4 hours. For a day trip or travel photography session, 128GB is the practical sweet spot and costs only a few dollars more than 64GB. If you shoot mixed RAW photos and video, storage fills faster than pure video sessions.
For international travel where buying a replacement card locally may be difficult or expensive, carry two cards. Start recording to card one and switch to card two when the first is full. This also protects you if one card develops a problem. 128GB plus a spare 64GB card is a practical travel kit that covers even intensive full-day shooting sessions without running out of space.

Stick to established brands: SanDisk Extreme, SanDisk Extreme Pro, Samsung PRO Endurance, Samsung EVO Select, and Lexar GOLD or SILVER series are all proven reliable for drone video recording. These brands publish verified performance specs and back their products with warranties. They appear consistently on DJI's official compatibility lists for multiple drone models.
Counterfeit memory cards are unfortunately common on Amazon and other marketplaces, especially for SanDisk products. Buy from Amazon directly or from a reputable authorized retailer rather than third-party marketplace sellers. If the price seems suspiciously low compared to what the same card sells for elsewhere, it may be counterfeit. Genuine SanDisk Extreme cards are widely available and not expensive. There is no reason to take the counterfeit risk.

Check DJI's official compatible microSD card list before buying. DJI publishes compatibility lists for each drone model in the user manual and on their support website. Not all cards that technically meet the speed specs are listed as officially compatible, and using an unlisted card introduces recording error risk. The SanDisk Extreme, Extreme Pro, and Samsung PRO Endurance appear on virtually every DJI drone compatibility list.
One more tip: format the card inside the DJI Fly app before first use rather than formatting it on your computer. Formatting in-app ensures the correct file system for the drone's recording software. After every major shoot, back up your footage before formatting. Treat the card as a temporary buffer, not long-term storage, and transfer footage to a hard drive or cloud storage after each session.
