The SanDisk Extreme microSD U3 Card is perfect for GoPro, Osmo Action, or drone users who need a fast card with high capacity that handles 4K video.
If you have a GoPro Hero8 or a DJI Osmo Action, you need a high-performance microSD card that can handle 4K video recording. The SanDisk 64GB Extreme microSD card is our recommendation.
The UHS-I/U3-rated SanDisk Extreme card offers read speeds of up to 160 MB/s and write speeds of up to 60 MB/s, so your footage can be captured, stored, and transferred quickly. It also comes with recovery software, so if you lose your footage, you may be able to get it back.
A reason why we recommend a U3-rated microSD card is because the card can sustain a higher reading and writing speed that U1 cards can't. And while you may think that a more expensive UHS-II offers better performance, you should know that the Hero8, Osmo Action, and many consumer drones, like the DJI Mavic Pro 2, can only support up to the top-end of UHS-I speeds.
For the price, the SanDisk 64GB Extreme microSD card is a great balance of performance and capacity. Besides 4K video, this card is great for time-lapse footage (or GoPro's new TimeWarp feature that speeds up video) or long-duration shooting. Having that ample storage also means you can shoot longer with a drone — we found 16GB to be far too little for drone flying. And because it's affordable, you can buy a few and swap them out when a card becomes full.
The card is also protected against shock, water, and X-ray. SanDisk is a reliable brand we've used and trusted, and the Extreme series is one of the company's best.
You can also use this card with your smartphone, tablet, or mobile gaming console — just make sure your device supports SDXC cards. In addition, the card is rated A2 for compatible smartphones and V30 for video.
Note that SanDisk makes an Extreme version of a 32GB microSDHC, which we've also successfully used in the Hero8 without issues. Also, older Hero cameras (prior to the Hero5) won't support SDXC cards to their full capabilities.
Pros: Ideal for Full HD and 4K video, UHS-I/U3, A2, V30, transfer speed up to 160 MB/s, includes SD card adapter
Cons: Higher capacities see a quick jump in price and can be quite expensive
