Rank #10 in Best 512GB MicroSD Card 2026: 10 Ranked, and Why Read Speed Misleads
Netac 512GB MicroSDXC Memory Card
Price and rating as shown on Amazon when we collected them. Both change.
The Netac MicroSDXC Memory Card 512GB is ranked #10 in our guide to the best 512GB microSD cards. It is a UHS-I card with a listed read speed of 100 MB/s and a write speed of 30 MB/s, and it carries a 4.5-star rating from 12,643 reviews.
The listing contradicts itself on speed class. The bullet says "speed Class U1/V10", the spec sheet lists "Class 10" and "V30", and the title claims "U3". V30 is required for 4K video, while V10 is only for full HD; U3 and U1 also differ in minimum write speed. This page uses only the figures and claims from the Amazon listing, not our own testing.
