Product Description

U1 means it’s a slow, low-end card？

Not always. Paired with V30, it can still offer great performance for 4K video.
U1 and V30 are the same thing？

U1 = 10MB/s, V30 = 30MB/s. V30 is stricter, and better for video.
If I’m using it for apps, A1 is enough？

A1 is fine for light-to-moderate app use. For heavy gaming or multitasking, go A2.
How to Choose a Card in 10 Seconds？
