SSDs in Raid 0 with Trim Support?

I'm running a Asus P67 Sabertooth board with 2 Kingston HyperX 120GB 3K SSDs in raid 0 in Windows 8.1 Pro. I've recently been reading bout the lack of Trim support with raid 0, so I need to know if Trim is actually being executed on these drives. How do I tell? Windows tells me its sending Trim commands, but how do I tell if the drives are executing them? I currently have the drives partitioned in half for windows and games, and I've already noticed a slow down in boot times after a month of use.
