Overview

The HP P-SDU128U3100HPMX-GE is a 128GB microSDXC memory card rated at Class 10 and U3, meaning it guarantees a minimum sustained write speed of 30MB/s — the threshold required for smooth 4K Ultra HD video recording. With sequential read speeds up to 100MB/s, transferring large files such as high-resolution photos and video clips to a computer or other device is noticeably faster than with lower-class cards. The UHS-I interface ensures broad compatibility with the vast majority of current smartphones, tablets, action cameras, and drones.

The card ships with a full-size SD adapter, extending its compatibility to laptops, desktop card readers, and DSLR cameras that use standard SD slots. At 128GB, it provides ample room for thousands of photos, hours of HD or 4K video, and a sizable library of apps and music. It is compatible with both Android and Windows-based host devices that support the microSDXC standard. For users looking to expand their device storage without the complexity of cloud subscriptions or external drives, this card provides a straightforward, plug-and-use solution.
