Raid 0 SSDs (Any Advice?)

[Icefire555]

So my setup is below for everything that I think is important regarding this.

I would like to raid 0 (2) Samsung 840 EVO 250GB SSDs.

However I have read things about SSDs not being able to trim on older raid setups. 

I currently run a asus sabertooth 990fx and an AMD phenom II x6 1090t. and although I haven't tested it to check,

I believe that trim is not working because my drives aren't in AHCI mode.

 

Will trim work on the x97 Mobo? I heard they added it back in the x7ish time period.

And is there anything I should take note of when doing this?

 

It will be a boot drive.

Not sure but - 

Z97, H97 & X99

 "If that isn’t enough for you, then you’ll also find a staggering 10-port SATA 6 Gb/s with RST and SRT support coming from the storage controller and SSD TRIM will be supported on RAID 0 configurations."
