Hey there, jbp195656!
Is it a hardware or a software RAID setup?
You should know that a fresh install of the OS is the recommended procedure when changing the boot drive.
I'm not sure it's going to work, unless you have the RAID connected to the same controller.
However, I think that having a single OS drive, preferably an SSD and larger drives for storage would be a much better setup. RAID-ing the SSDs is only good if you are using more than 2 in the array. RAID 0's speed won't be that noticeable unless you are working with raw video editing. If you have another HDD, you might want to consider RAID-ing that, instead of the SSDs.
