Device manager shows "non AHCI mode" so ahci is probably not enabled.I'm using Ubuntu for several reasons, I do not like Microsoft to their attitude, I'm tired of virus and spyware, Ubuntu is free, Ubuntu is much faster even with the ssd.
Well if your stuck on that OS than you need to find out does it support TRIM, and does it support Intel's SSD TOOL BOX, If it does than you can optimize your SSD Manuely. you should run the tool box at lease once a week. Than use ATTO to test the SSD ,It's a free download just gogle it.
Microsoft has a Article # 922976 , That tells you how to change fromIDE or RAID , TO AHCI without reinstalling the OS ,Don't know if it's the same with umbuto . other wise you have to reinstall the OS to change it.
