Some users here think that USB hard drive support is pointless for portable mode - you are wrong.
I play 99% in portable mode and this feature for SXOS is the best thing ever for CFW users:
You can use a USB-C adaptor (only a few dollars on Amazon) to connect your hard drive to your Switch and install games. It's faster than Wifi-FTP, also you don't need to remove the SDcard to copy those big retail games (14+gb). That means you won't have to reboot and do all those RCM, payload BS. After NXShell updated with USB support (or TX add a file manager), you can even copy XCI to your SDcard. This makes it so easy to swap games if you are low on SDcard space.
I personally will not play games with a hard drive attached to Switch's USB-C port, it will drained the battery. But using it to install/copy/swap files is so easy.
