Ready-to-use, fast and reliable storage for ATOMOS® 4K video workflows 

Atomos® creates easy-to-use solutions that merge recording, monitoring, and playback into a single touchscreen device to enable faster, higher-quality, more affordable video production, but the trip from recorder to editing can vex video professionals on tight production deadlines. The Atomos Master Caddy® by G-Technology® streamlines the Atomos workflow. 

With SSD configurations achieving transfer rates surpassing 500 MB/s (ideal for 4K, HDR and other demanding content formats), the Atomos Master Caddy inserts directly into any Atomos-compatible recorder. The caddy then slides into the ev Series Reader Atomos Master Caddy Edition, which slips into any G-DOCK ev® or ev Series Bay Adapter. The Atomos Master Caddy by G-Technology makes quick, cable-free work of transferring footage into main project storage, creating backups, and quickly turning around formatted media. *
