128GB microSDXC card for Android apps and 4K video

This ADATA Premier Pro microSDXC card offers 128GB capacity with UHS-I U3, Class 10, V30 and A2 ratings. Sequential read speeds reach 100MB/s while write speeds hit 80MB/s. It targets smartphone users who need faster app loading and camera owners recording 4K footage.

SD adapter extends use to cameras and laptops

The bundled SD adapter lets the microSD card fit full-size slots in digital cameras, video recorders and card readers. This means a single card can move between a phone for A2 app performance and a camera for V30 sustained video capture without buying separate media.

Verify host device supports UHS-I and A2

Check that your phone, tablet or camera explicitly lists UHS-I and A2 compatibility to gain the stated speed and app-performance benefits. Devices limited to older speed classes will fall back to slower rates. The card operates from -25°C to 85°C for harsh environments.

Questions about this item

How often should I replace this 128GB card if I use it daily in a dashcam?

The card is built for repeated recording with automatic error correction and rugged durability including waterproof, shockproof and temperature resistance from -25°C to 85°C, so it handles daily dashcam use without a fixed replacement interval.

What is the first limit reached during sustained 4K video recording?

The V30 rating guarantees a minimum write speed of 30MB/s, so the sequential write ceiling of 80MB/s is the first limit that appears under continuous high-bitrate capture.

Does the card get hot or draw extra power during all-day recording?

It operates passively with no moving parts and is rated for -25°C to 85°C, so it stays cool and draws minimal power even during extended Full HD or 4K recording sessions.
