Professional GOLD microSDXC UHS-II 128GB

The Lexar Professional GOLD microSDXC UHS-II card provides 128 GB of storage for professionals and enthusiasts who capture high-resolution drone footage, action camera recordings, or portable gaming content. It carries a Class 10 speed rating and operates reliably from -25 °C to 85 °C.

UHS-II interface for rapid workflow

The card delivers read speeds up to 280 MB/s and write speeds up to 100 MB/s at this capacity, enabling quick file transfers and smooth 4K UHD video capture. A UHS-II card reader is required to reach the quoted read performance, freeing time during post-production offloads.

Users who need guaranteed minimum write speeds for extended 4K recording will benefit from the V60 rating. Buyers whose devices only support UHS-I or who require capacities beyond 128 GB should consider other options.
