Playing with disk settings

[Steiner-SE]

I wonder about the available disk settings, which are safe to play around with and which should be avoided at all.
I'm thinking of:
HDD Standby (guessing always on)
Advanced Power Management
Acoustic Level

In addition to suggested settings, what exactly does each do and how will it affect performance a

Advanced Power Management (APM) and Automatic Acoustic Management (AAM) require hardware support from the drive. If the drive doesn't support it, those settings do nothing. To see if a drive supports APM and/or AAM, look at the output of camcontrol identify <drive ID>:

Code:

Feature                      Support  Enabled   Value           Vendor

advanced power management      no       no
automatic acoustic management  no       no

Thank you, the results from testing all drives was meager. None supported AAM and only a few supported APM.
The 2 Crucial 120Gb boot SSDs, the 3 Seagate IronWolf 4Tb and the two Toshiba 4TB supports APM.
The 3 IronWolf 12TB, the WD Red 4TB doesn't support either.
