Seems to relate to an AMD SATA driver issue: https://communities.intel.com/message/178408#178408
Be careful uninstalling storage drivers, if the Microsoft AHCI driver isn't active, you could end up in a no-boot scenario.

We understand the Intel® Solid-State Drive Toolbox detects your SSD as in a RAID array and it won't let you use all the features.
First of all, it is important to mention that since Windows* 7 and later, the optimizer option is not required, as the operating system does the TRIM function by default.
As the previous user mentioned as well, this situation has happened before with AMD SATA drivers. Checking on your logs, we do see the AMD driver installed.
You could follow the suggestion of uninstalling the driver, but we cannot guarantee this will work or that your SSD will boot normally.
It worked for years, then didn't. Blaming an AMD driver, if it makes you happy, is OK I guess. I applied a different solution. Intel SSD Toolbox is now uninstalled since it doesn't appear to add any value.
