How Can You Check if Your SD Card is V30?

When shopping for an SD card, it’s essential to check for the speed class marking to ensure it meets your needs. On an SD card with a V30 rating, you’ll typically see the “V30” symbol printed on the front of the card. This symbol indicates that the card is part of the Video Speed Class and guarantees a minimum sustained write speed of 30 MB/s.

If the card is not explicitly labeled with the V30 symbol, it may be using another speed rating system, such as UHS (Ultra High Speed). The U3 label, for instance, indicates a minimum sustained write speed of 30 MB/s, which is equivalent to V30 in terms of performance. However, if you want to ensure compatibility with 4K video and video-focused applications, it’s always best to look for the “V” class symbol.
