Are you really considering building an madm RAID with USB drives?
Technically it is possible but I doubt you'll get anything but problems with reliability.
It's easier than you may think to compile yourself - check out https://docs.armbian.com/Developer-Guide_Build-Preparation/
If you're looking to 'play' with mdadm as a learning exercise then fine, but if you really value your data I'd suggest you should build a 'proper' raid using an x86 board and good quality SATA drives.
On budget SoC boards I'd just rsync my precious data across several physical drives.
 

Hi Guys,
I'm new to the forum here but have been using [only] Armbian on my various OPi boards for some time.
I'm now waiting for an OPi3 board to arrive from Aliexpress and so I've been following this thread with interest.
I've now successfully built Stretch images from the dev sources but with no hardware yet to test I'm restricted to keeping up with the posts on here.
Many thanks to everyone who has already contributed to what I reckon is going to be a pretty awesome board for the price.
