Overview

The SanDisk SDSDQUI-128G-A46 Ultra microSDXC offers 128GB of storage in the compact microSD form factor, backed by Class 10 and UHS-I speed ratings. This combination guarantees a minimum sustained write speed of 10 MB/s, making the card well-suited for everyday photography, standard-definition and 1080p video recording, and general file storage. The included full-size SD adapter extends its usefulness to any device with a standard SD slot, from DSLR cameras to laptops and desktop card readers.

As a UHS-I card, the Ultra sits in the mid-tier performance bracket — fast enough for reliable day-to-day shooting but not intended for the demands of continuous 4K video or rapid burst-mode photography where higher-rated V30 or UHS-II cards are recommended. The 128GB capacity strikes a practical balance between price and storage space, holding thousands of high-resolution images or hours of HD video before needing to offload files. The card ships pre-formatted in exFAT for immediate use in SDXC-compatible devices.
