Our take on the Samsung Pro Plus U3 A2 V30 microSD XC Memory Card w/ Reader
The Samsung Pro Plus is a microSDXC card rated U3, A2 and V30, sold here with a USB card reader. That combination targets people who shoot 4K video or run apps and games from a card: U3 and V30 cover sustained 4K recording, and A2 speeds up random reads and writes for app data. Samsung rates the line for demanding use, with protection against water, temperature extremes, X-rays and magnets. It sits above Samsung's Evo Select line and competes with SanDisk Extreme and Lexar Professional cards on speed ratings rather than on extras.
- U3 and V30 ratings suit 4K video capture
- A2 rating helps app and game load times
- Bundled USB reader lets you offload footage without a card slot
- Samsung rates it for water, temperature, X-ray and magnetic resistance
- Backed by a long Samsung limited warranty

What reviewers say

- ReaderPraisedThe included USB reader is seen as handy for offloading footage to a computer.
Questions and answers
- Is this card good for 4K video?
- Yes. The U3 and V30 ratings cover the sustained write speed 4K recording needs in phones, action cameras and drones.
- What does A2 mean?
- A2 is an app performance rating for random read and write speed. It speeds up apps and games stored on the card, but only on devices that support the standard.
- Does it come with an SD adapter?
- The bundle includes a USB card reader, not a full-size SD adapter. You need a reader or slot that takes microSD directly.
- Will it work in a Nintendo Switch?
- Yes. The Switch takes microSDXC cards, and the A2 rating helps game load times.
- How does it compare with the Evo Select?
- The Pro Plus has higher speed ratings and better endurance for continuous 4K recording. The Evo Select is the cheaper line for lighter use.
- Is the card water and shock resistant?
- Samsung rates it for water, temperature, X-ray and magnetic resistance, so it tolerates typical camera and phone use.
