Recently installed a MX100 256GB into a netbook replacin the old spinning drive. Reading these forums I noticed that the APM setting is quite important. I checked the value using CrustalDiskInfo and found the value to be 0001h. I set it to the value 00FEh and continued as normal, recently I did a AS-SSD benchmark and noticed severely degraded results, I checked the APM value and it had reverted to 0001 again.
At this point I put it back to 00FEh and since then it has maintained that setting. Am just curious as to what may have caused it to downgrade to 0001?
SSD: MX100 256GB Firmware: MU02
OS: Win 10 Home - clean install
SATA version: 2 (3Gbs)
SATA driver: storahci
Power setting: High performance with min cpu changed to 5% from 100% to allow CPU idle and time out on hard drive set to Never.
Thanks for ant suggestion or info on this subject.

I'm not sure what it's important for? Mine is whatever default is, and there's not a general recommendation around here to change it. It might be a troubleshooting thing for something rare?
But IIRC, it's not a setting that survives a reboot. You need software that resets it each boot.
A quick google suggests you probably want a program called HD Parm in your computers startup.

the value seems stable now between reboots without any special software, I think it changed originally when I was messing with the policies tab for the drive in device manager.
