micro sd card a2

A2-rated cards are commonly listed alongside Class 10, UHS-I/U3, and Video Speed Class V30 ratings.

They’re described as supporting Full HD and 4K/4K UHD recording. Cards bearing U3 and V30 ratings are cited for sustained 4K capture, and some listings note suitability for long continuous recording.

Many listings advertise water-, shock-, temperature-, and X-ray resistance; some also list static- and vibration-resistance.

Some listings include an SD card adapter alongside the microSD card.

Warranty coverage varies by product: some cards list a 1‑year limited warranty while others list a 5‑year limited warranty.
