When I originally built my PC with a DZ68DB board, I added a Intel SSD 311 20G ssd to use as a cache. So the BIOS specifies RAID since I was using Rapid Storage Technology to form a RAID with my SATA drive.
I have now disabled RST and removed the 20G ssd cache drive. I cloned my old SATA boot drive to a Samsung 850 Pro SSD. In the BIOS where RAID is marked (vs IDE or AHCI), it says in the help description that RAID always includes AHCI. So am I losing any functionality/performance (like TRIM) with my SSD leaving the BIOS configured with RAID option? The Samsung Magician software gives a warning that performance will be less since it is not in AHCI mode, but not sure if that is a general warning and not always true based on the bios description for RAID.
I definitely don't want to reinstall WIndows and prefer not to play around with the registry to switch to AHCI unless it will make a big difference.
Thank you
