Look at the output of "cat /proc/mdstat". mdraid may still be working to

Looking at /proc/mdstat I see that it's chugging away while root
returned to
its shell prompt in 8 seconds.
/proc/mdstat tells me that 'resync = 1.8% (37030848/1953383488)
finish=1550.7min' (at that time) so it will be about 26 hours before it's
finished.
Since this process is owned by root will it continue after I log out? I
assume so but don't know for certain.
This is normal. mdraid works at the kernel/device driver level. It
will keep doing its thing as long as the system is up. Even if you were
to shut it down, it would pick up where it left off upon rebooting.
BTW, what you are seeing is likely not a process, but rather a kernel
thread. IIRC, the ps command shows kernel threads by enclosing them in
square brackets. For example:
[galens@zinc ~]$ ps aux | grep raid
root 572 0.0 0.0 0 0 ? S< 2020 557:05 [md1_raid1]
root 577 0.0 0.0 0 0 ? S< 2020 1:47 [md0_raid1]
Regarding the type of RAID to use, and based on my limited understanding
of your goals, I think you just want a simple RAID1 array.
