Alderan, you have to enable DSA on you bios first
Unfortunately I noticed no changes.
The only thing I noticed about DSA setting was that when in automatic mode my c-states were always disabled even when windows was set to power saving profile.
Thanks for the heads up, !
You are correct on all accounts:
1. Once I've enabled the DSA (Dynamic Storage Accelerator) option in my BIOS, I was presented with an alternate Performance tab settings window:
2. At this point I should mention, that my current Windows' Power Options Power Plan is based on 'High Performance', except for the following changes:
- Display is set to never go to sleep (instead of the default 15 minutes).
- In the advanced options of the Power Plan:
A. Hard Disk is set to never go to sleep with '0' (instead of the default '20' minutes).
B. Processor power management>>Minimum processor state is set to 5% (instead of the default 100%).
3. I've made sure that Link Power Management is still set to Disabled.
4. I then started cycling through the different Intel RST DSA configuration options.
5. At each change (Automatic / Manual and its 3 accompanying sub-profiles), I:
A. Rebooted the machine and let it load the OS.
B. Shut down the PC.
C. Disconnected the PSU from the wall outlet.
D. Clicked the power button on my PC case 3 times to be sure that most of the current has discharged.
E. Powered the PC again, let it load the OS and checked if the issue still persisted.
6. No change was observed in terms of the excessive loading/unloading behavior of my 3 mechanical hard drive heads.
7. For now, I'm reverting my OS to my image back up of Intel RST v12.9.2.1000 and I'll also disable the DSA option in my BIOS, as it was before.
In any case, I'd be happy to do some more tests.
