I read in older guides, that pretty much all guides i read explains on how to prepare and format a new USB drive in order to install addons...

I am using a new RT-AX86U with Merlin, and wondering if in 2021, it is still actual to use the USB3.1 port, with a good brand USB 3.1 Thumb Drive and force it to use USB2?

Why is that? I mean why forcing it to use USB2 over USB3, any reason?

Possibly to reduce interference with the 2.4 GHz band. Some of us have found that the older USB2 drives last longer than some newer USB3 drives. Thumb drives that is. I have an old PNY 2 GIG USB2 drive that I have used on at least three Asus routers. Just set it up today with a swap partition and an EXT4 partition (for traffic data) to use on Merlin 386.2 beta 3.
