Our take on the Onn Class 10 Flash Memory Card

The Onn Class 10 microSD card is a budget memory card sold by Walmart's house brand. It carries Class 10, U1, V10 and A1 ratings, so it handles Full HD video, burst photos and app storage on Android phones, tablets, drones and the Nintendo Switch. Read speed is rated up to 100 MB/s and minimum write speed 10 MB/s, which is modest next to U3 cards but fine for 1080p recording. It ships with a full-size SD adapter, something budget rivals often leave out. Reviewers rate it decently for everyday use, though some report slower real-world writes and occasional card failures, so it suits casual users rather than 4K shooters.

About the Onn Class 10 Flash Memory Card

Add room for more photos, videos, apps, and files with the onn 32 GB microSDHC flash memory card. It gives your phone, camera, tablet, computer, drone, or Nintendo Switch extra storage to capture and carry more of what you use every day. At 32 GB, the card holds approximately 5,420 20 MP photos or 7 hours of Full HD video, with the exact amount varying by your host device's resolution and compression. Actual usable capacity may vary because some of the listed capacity is used for formatting and other functions; for flash media devices, 1 MB equals 1 million bytes and 1 GB equals 1 billion bytes. Rated Class 10, U1, V10, and A1, the card offers up to 100 MB/s read speed for moving files off the card and a 10 MB/s minimum write speed for recording. These ratings support continuous burst-mode photography and Full HD video recording. Stated speeds require a compatible host device capable of reaching them, and performance and photo/video support may vary by host device, settings, and configuration. A full-size SD adapter is included, so the same card also works in cameras, laptops, and card readers built for standard SD card slots—no separate adapter to buy. See the features below for the full list of supported device types, Nintendo Switch models, and durability test conditions. Covered by onn's Limited Lifetime Warranty.
