The video speed class (V30 / V60 / V90) tells you the guaranteed minimum write speed – that is what your camera needs for video. The “up to” read speed on the label only shows how fast you can copy files to the computer.
| Label | Minimum sustained write | Typical use |
|---|---|---|
| V30 | 30 MB/s | Full-HD and most 4K video |
| V60 | 60 MB/s | 4K and high-bitrate 4K video |
| V90 | 90 MB/s | 8K, All-I and RAW video modes |
| U3 | 30 MB/s | older equivalent of V30 |
| A1 / A2 | app performance | apps stored on the card (phones, consoles) |
UHS-I vs UHS-II: UHS-II cards have a second row of contacts and are much faster in UHS-II cameras and readers. They also work in UHS-I devices, but only at UHS-I speed. Always check what your camera manual requires for the video mode you use.
Yes, the V30 rating covers most 4K modes of consumer cameras.
No, it is a UHS-I card – it works in all SDXC-compatible devices.
