This comparison covers the performance, cost, features, and maturity of HDMI-CEC and USB storage protocols
Updated June 28, 2026
HDMI-CEC
Best when consumer device connectivity and simplicity are top priorities
USB
Best when high-performance storage and wide compatibility are required
USB's superior performance, wider compatibility with storage devices, and established infrastructure make it the better choice for most storage needs. HDMI-CEC's wider compatibility with consumer devices and simplified connectivity are advantages, but its slower performance and limited compatibility with storage devices make it less suitable for demanding applications.
