I have a Raspberry Pi 5 8GB model configured to use a NVMe SSD as my primary boot device. I also configured my boot sequence so that I boot from the SD Card first, USB attached device second, and NVMe SSD third. I set the boot order in this manner so that I can override always booting from the NVMe SSD. Be that as it may I am thinking of changing the USB_MSD_DISCOVER_TIMEOUT parameter value from a default of 20 seconds down to the minimum of 5 seconds in order to reduce the overall boot time. Before I try that I wanted to ask some questions please:
1- Is there any downside of reducing the TIMEOUT from the default of 20 seconds down to 5 seconds?
2- A TIMEOUT of 20 seconds seem to be quite high. What might be the rationale for such a high value? Is it to account for non-SSD devices that might be USB attached to a Pi?
Thank you for any feedback in advance!
