Angelbird's Atomos Master Caddy 4K RAW is an SSD designed to interface directly with Atomos Master Caddy products that support 4K video. This model has 1TB of storage, and will record high-resolution 4K RAW as well as HD video. Atomos's Sumo, Shogun, and Ninja series recorders in the Inferno, Flame, Studio, and Assassin categories will support these drives, and since they are self-contained, no assembly is required.
