Last time I "booted" on software RAID it was not really on the RAID.
There were simply 2 exactly the same partitions on both drives that were
boot.  But if you removed a drive, then you had to go into BIOS to tell
it to boot from the other drive because it was not truly RAID at that
point.  Just duplicate.  Plus if you change the boot you have to
remember to copy it to both drives.

Unless the RAID driver is now somehow included in the boot manager!?

I don't wait for hours if the drive was properly shut down.  When I did
software, that took a long time too if you did not properly shut things
down.
