SanDisk Extreme microSDXC UHS-I Card
The middle ground between everyday storage and Extreme PRO
Faster than a standard card, without paying for headroom you may not need.
The SanDisk Extreme microSDXC UHS-I card is where we point customers who’ve outgrown a basic Ultra card but don’t need our top-tier Extreme PRO line – action cameras, drones and phones that shoot a lot of 4K, in capacities from 64GB to 1TB.
Available capacities: 64GB | 128GB | 256GB | 512GB | 1TB
Out in the Field
Action cameras don’t get a second take. The V30 rating guarantees a sustained write speed while recording, and the card itself is rated shockproof, waterproof, temperature-proof and X-ray-proof – built to survive wherever the camera does.
Up in the Air
A drone flight doesn’t last long, but the footage adds up fast at 4K. Having enough headroom on the card means you’re not stopping mid-flight to worry about space.
In Your Pocket
The A2 rating (up to 4,000 read IOPS, 2,000 write IOPS) is what actually matters for a phone – it’s the difference between an app that feels sluggish running from a card and one that doesn’t feel any different from internal storage.
Choose Your Capacity
| Capacity | Best For | Recommended Use |
|---|---|---|
| 64GB | Everyday action | Full HD/4K video, action cameras |
| 128GB | Mobile creators | Smartphones, cameras, drones, gaming |
| 256GB | Content creators | 4K video, photography, drones |
| 512GB | Heavy users | Long 4K recordings, travel, professional content |

Tip: if you regularly shoot 4K video or travel without a computer to back up to, 256GB or larger is a practical choice.
