External USB Storage
Some external USB storage devices have different writing speeds, which
may affect the recording time. Check the specifications and performance
of the external USB storage device before connecting it to the camera.
If a USB 3.0 storage device is connected to the camera's USB2 connector, the trans-
fer rate will be limited to the USB2 standard.
Some external USB storage devices may display two icons for one device, as shown in the
example.
In this case, the right icon can be used to save, remove, or display capacity.
