Do you also use the ROCKPro64 Metal Desktop / NAS Casing or something else?

OK. I understood that.
Please tell me the right command to configure on for example 128 or 192. Is that correct? --> ./openSeaChest_PowerControl --device /dev/sda --setAPMLevel 128

And the right command to configure spindown time. I want to set 30 to 60 minutes. Is that possible?

You posted the 'Power Cycles' of your disks..
And that is  a preoccupation, because you have ~3000-5000 'Power Cycles'( SMART attribute 12, the Load/Unload is SMART attribute 193 ).

That tells me that, your disks fail to start a lot of times due to not sufficient power budget..
Probably because they are in 'Performance' Mode..

I'll test that with for blockid in {a..d};do smartctl --attributes /dev/sd${blockid}|grep -E "^ 12|^193"; done for a week.
