Several things you should try. Are you using the Intel SSD Toolbox? If not, download and install it:
Be sure to perform the system tuning option, which could fix and power setting issues.
Do you know what Windows Power Option you are using? Go into Power Options from Control Panel, and choose High Performance plan. Or if you rather used Balanced, click Change Plan Options, and then Advanced Options, and under Hard Disk set Turn Off Hard Disk to Never.
See how that goes, and we can take it from there if necessary.
