I have a powered USB dock with a couple of SATA drives configured as RAID1, and used only for nightly backups. The (minimal) manual for the dock tells me it will power down after 30 minutes idle time, however I don't see this happening. I presume that something (such as the md system) is touching the drives periodically.
First: dnf install blktrace then start a (replace sda with one of the disks) btrace /dev/sda and keep it running when no activity is expected. It will tell you what is touching the drive, including any RAID reconstruction or check. You could also run the command on /dev/md0 (or what is named), to see if something is accessing the RAID through the filesytem (e.g. df, updatedb, ...).
