Current specs:

*x58 eVGA e758 w/ i7 930 @ 4.2GHz
*Windows 7 x64
*Samsung 840 Pro 256GB SSD
*WD Blacks (storage)
*AHCI mode (BIOS)
*Intel driver v11.2.0.1006

I think I'd like to:

*Reformat my SSD and install a fresh Windows 10 Pro
*Create a RAID with secondary/storage drives (with my primary/OS drive being a single Samsung 850 500GB SSD)

Two questions:

1.) Any suggestions on the best driver to use, as well as a preferred order of setup (RAID vs AHCI, installing/updating a controller driver, when to create the storage array, etc.)?

2.) Is there any downside to switching from AHCI to RAID in my BIOS, assuming that my primary OS drive will be a single SSD? I heard that TRIM can't be done via RAID, along with other downsides, but I'm not sure whether that only applies to what's RAIDed, or if it applies to all drives when RAID mode is activated.


EDIT: I plan on reformatting this week, however, I won't have the storage drives to create a RAID until next month.
