ultra data

Listings show capacities from 32 GB up to 256 GB. The most common sizes across these cards are 32 GB, 64 GB, 128 GB and 256 GB.

Many listings list UHS Speed Class 3 (U3) and Video Speed Class V30. Other common markings include U1 and the legacy Class 10 rating. Specific ratings vary by model, so check the product details for each card.

Warranty language varies between listings. Some product bullets specify a “1 Year Limited Warranty,” while at least one description references a “limited lifetime warranty.” Several listings do not state warranty length in the brief bullets — always review the product page or manufacturer terms for the exact warranty coverage.

Listings often mention proprietary offload features or recommend using a high‑speed (professional) card reader to achieve the advertised top read speeds. Example listings cite offload/read speeds in the high‑hundreds of MB/s range (commonly around 180–200 MB/s) when paired with a compatible reader and host device.

A subset of the microSD/microSDHC/microSDXC listings explicitly state Application Performance Class 1 (A1) support. Those entries note the A1 spec’s focus on improved random IOPS and better app performance on mobile devices.

Listings recommend these cards for mobile app storage, action cameras and extreme‑sports recording, Full HD and 4K UHD video, 3D video, sequential burst photography, and general photo/video file storage.
