So it is possible. Writes are done to all three drives.
Reads from the
fastest drive. This way two drives can fail and the show
still goes on.



So would it be better to mirror all 3 drives in RAID-1, or set the third up as a hot spare?

The only reason to run all 3 drives mirrored would be if you periodically swap one out to keep as a backup.
