Class 10, U1, and U3 all refer to different types of memory cards. Here are the main differences between them:
- Capacity: Class 10 and U3 cards are designed to handle higher capacities than U1 cards. While U1 cards are typically available in capacities up to 128GB, Class 10 and U3 cards can reach as high as 512GB or even 1TB.
- Speed: Class 10 and U3 cards are faster than U1 cards when it comes to read and write speeds. A Class 10 card has a minimum sustained write speed of 10MB/s, while a U3 card has a minimum speed of 30MB/s. U1 cards are slower, with a minimum sustained write speed of only 10MB/s.
- Use cases: Because of their higher capacity and speed, Class 10 and U3 cards are better suited for tasks that require large amounts of storage or fast read/write speeds. This includes recording high-definition video, shooting burst photos, or running apps directly from the card. U1 cards may be sufficient for basic use such as storing music or documents.
- Price: In general, you can expect to pay more for a Class 10 or U3 card than a U1 card due to their higher specifications and capacities.
- Compatibility: It's important to note that not all devices will be able to use Class 10 or U3 cards due to their increased power and data requirements. Always check your device's specifications before purchasing a memory card.
