Personally I would use the three devices as a RAID-10 which would

RAID 10 requires 4 drives:
Not Linux implemention of RAID 10, which requires at least 2 drives.
Do you have a URL or man page that describes this?

Thanks for the pointer. STFW:

"... a nonstandard definition of "RAID 10" was created for the Linux
MD driver ..."
https://en.wikipedia.org/wiki/RAID#Non-standard_levels
https://en.wikipedia.org/wiki/Linux_MD_RAID_10#Linux_MD_RAID_10
So, "Linux MD RAID 10" can be RAID 1, RAID 10, or something totally
different.
Co-opting and redefining standard terms is bad engineering.
