Wow, this question takes me back to like the 00’s when laptops had battery life measured in minutes.
Don’t do that
Why?
Creates a bunch of extra wear on the drives. They’ll die very fast. Keep them spinning.
This is what I would think instinctively too, but still asked as I did not know if my instincts are correct. It’s like starting and stopping the car engine on every traffic light…
Seriously, I don’t know if this is precisely accurate but definitely don’t spin down. Data errors, software problems if it has to wait for spin up and then something experiences a timeout.
I’ve had some drives spinning for like twenty years without any problems.
Spin down when not in use is normally default behaviour for most systems already, you don’t need to do anything.
You can use hdparm with the -S parameter to set the standby/spindown time for a hard drive.

Hdparm: https://wiki.archlinux.org/title/Hdparm
E.g:
hdparm -B 127 /dev/sdaI know it’s archwiki, but it’s the same on every distro
umount maybe
Correct answer.
After setting the spin down timer using hdparm, unmount the drive and it will spin down accordingly.
This also makes sure you are not spinning down drives just for a few minutes of rest.Now just if my SSD were not heating itself to 40℃ when at its lowest power mode when unmounted…
