So after spending all night redoing my raid to the Gigabyte Ports and putting my Intel ports to AHCI for TRIM I found this:The Thread
But here is the quote:
The latest: Intel® RST 9.6 will be released this week which includes TRIM support for SSDs. It will support TRIM with SSDs in an AHCI configuration, or with the RAID controller enabled and the SSD is used as a pass through device. An example of this use case is for users that want to use the SSD as a boot drive but still be able to RAID multiple HDDs together to allow for large protect data storage
– a great use for the home theater PC. TRIM support for SSDs in a RAID configuration is under investigation and is not included in Intel® RST 9.6.
Translation: if your Intel storage controller is set to RAID mode, you'll now be able to benefit from your solid-state drive's TRIM functionality when running it alongside a RAID array comprised of mechanical drives. TRIM isn't supported for SSDs participating in a RAID array, however. Intel may add that feature in the future, but it hasn't committed to doing so.
Thanks Pings and DannyM for making me researching it further.
To summarize (assuming that your SSD is TRIM-Capable):
SSD + ACHI Mode + Windows 7 Driver = TRIM
SSD + ACHI Mode + Intel Driver = TRIM
SSD + ACHI Mode + NVIDIA/AMD/VIA Driver = No TRIM
SSD + RAID Mode + Non-Intel Driver = No TRIMSSD + RAID Mode + Intel Driver = TRIM
SSD RAID = No TRIMThis driver update is really important only if you have individual SSDs and RAID of HDDs.
Which was exactly what I was doing... So did I not undo everything for nothing...
