Requires understanding of Linux, Chrome OS, Ubuntu, and RAID configurations.
Expanding storage on Ubuntu 16.04 is possible using a USB stick, but you need to understand the setup. You can connect both the system drive and the USB together, though it’s best to use a bootable USB for reliability. Duel booting won’t break the raid setup, but ensure your system is properly configured. Installing Chrome OS and Gallium OS on the raid partition is feasible, as long as you allocate enough space and manage partitions correctly. Adding extra USB sticks inside the system is also an option, but verify compatibility with your BIOS and OS version.
You might consider using LVM or ZFS, but it could slow down your whole system. A USB SSD would likely perform better, and installing the OS directly on it would be ideal.
