Hi, I have a 16gb optane module in my laptop. After installing a fresh copy of Windows 10 and successfully enabling Optane for hdd acceleration with Intel RST software my hdd now spins down and up during computer use and there are often times whenever I open up a new program or suddenly perform a function in an already opened program (such as highlighting text in adobe pdf or right-clicking in Microsoft word) the hdd seems to turn back on or accelerate (increasing spinning sound) and this is accompanied by a lag during such simple tasks. I didn't have this issue (of recurring lag when using/opening simple programs) prior to enabling Intel Optane. Apart from that, the Intel RST program shows that everything is functioning normally. I already tried disabling Link Power Management in the RST application but that didn't fix the issue.
We have discussed the problem on Intel's support forum already and their technician wrote the following:
"Please try to get a BIOS update with an updated OROM. This is necessary and could be causing issues like the ones you are currently experiencing. If not then this could point at a SATA controller issue which should be addressed by the manufacturer of your system. Please contact them so they can check this."
I have the latest BIOS Version: 1.09 installed and that doesn't fix the issue.
All Intel's drivers are also the latest version.
After a lot of time spent experimenting and searching through the Internet I've discovered that it is something to do with hdd's APM (Advanced Power Management) settings. For example, if you create a key in Windows registry at
then HDD won't spin down every 10-20 seconds of inactivity. It fixes the problem, but i guess there should have been no such issue from the beginning.
Thanks in advance!
