Hi @RSG93
Welcome to the Roku Community!
We understand your inquiry about the Roku Streambar Pro.
Please be aware that a SD card may reduce the loading time of channels on a Roku device. However there are a variety of factors that would affect load time of a channel, such as how many channels are on your Roku account. How many channels do you currently have linked to your Roku account?
Please keep us posted and we will be more than happy to assist you further.
All the best,
Arvy
