UHS speed classes indicate the minimum write speed for video recording. U1 guarantees at least 10MB/s, suitable for Full HD video. U3 guarantees at least 30MB/s, required for 4K video. For 8K, look for V60 or V90.
UHS-I cards have a maximum theoretical speed of 104MB/s (with UHS-I bus), while UHS-II cards can reach up to 312MB/s. UHS-II cards have an extra row of pins for faster data transfer but require a UHS-II compatible reader to achieve full speed.
Yes, but performance may be limited by the adapter. For best results, use a card that matches your device's native format. Some adapters may not support UHS-II speeds.
Consider your device's maximum supported capacity and your storage needs. For 4K video, 64GB or 128GB is common. For 8K or long recordings, 256GB or higher may be needed. Always check your camera's compatibility.
If you shoot 4K video or continuous RAW bursts, choose a U3 or V30 rated card. For 8K, look for V60 or V90. For basic use, U1 is sufficient.
Check if your camera supports UHS-II for maximum speed. If not, a UHS-I card will work fine. Also, ensure the form factor (SD, microSD) is correct.
Higher capacities offer more storage but cost more. Balance your needs: 64GB is a good starting point, while 128GB or 256GB is better for heavy use.
| Feature | Why it matters |
|---|---|
| Read/Write Speed | Determines how fast data can be transferred. Higher speeds reduce wait times for file transfers and improve camera buffer clearing. For 4K video, write speeds of at least 30MB/s are recommended. |
| Speed Class Rating | Indicates minimum sustained write speed for video. U1 (10MB/s) for Full HD, U3 (30MB/s) for 4K, V60 (60MB/s) for 8K. Ensures smooth recording without dropped frames. |
| Durability | Cards that are temperature-proof, water-proof, shock-proof, and X-ray-proof are essential for outdoor use. They protect your data in harsh conditions. |
| Capacity | Larger capacity allows storing more photos and videos without swapping cards. However, higher capacities can be more expensive and may not be supported by older devices. |
