Silicon Power Superior Pro microSDXC UHS-I Colorful U3 512GB Card Review
 

The Superior Pro Colorful U3 512GB card has obtained great performances in our speed tests, trailing the 256GB variant. 4K recording is no issue at these speeds and 512GB is nice to have when recording lots of hours from a single session. Additionally, the card is dustproof, waterproof, temperature-proof and X-ray-proof for use in extreme environments and is equipped with ECC functions as well.
