The Gigabyte B660I Aorus Pro DDR4 is a well-rounded Mini ITX B660 board with four SATA ports, a single M.2 socket, overkill power delivery, and a premium appearance with integrated RGBs. It’s missing a 20 Gbps USB port, and the $245 seems high for what you get.
Good to see you guys doing more mATX and ITX board reviews.
One suggestion on motherboard reviews. Test the M.2 performance and one of the higher speed USB 3.2 ports.
I've noticed on other sites, some motherboards can have much slower real world performance on the M.2 and USB ports than otherwise identically setup boards with the same chipset.
I believe this is why some of your boards are showing up under performing on the compression tests. The differences in this area can be significant. Example below.
