It depends whether the host adapter and port support hotplug. On some motherboards it must be enabled in BIOS/UEFI settings. Do not disconnect a disk while power is on if the port does not support hotplug either.
Also I see problems with the device naming as long as no hd uuids are not used by having a drive appearing as /dev/sdx and with next reboot as /dev/sdn. Are my concerns reasonable or am I just too afraid?
/dev/sd* names are not persistent and cannot be relied upon. But md uses UUIDs for assembly, so it does not matter.
