Plug-and-Play Storage for PC & Mac

USB-Powered Convenience
Because this drive draws power directly from the USB connection, there’s no need for a separate power adapter. That means fewer cables to carry and no extra power sockets required—perfect for travel, fieldwork, or tight desk setups. The single-cable design also speeds up setup and reduces clutter.
