I don't have 2 SSDs but I've got 3 HDDs in RAID0 on the software side, using Windows Disk Management.
Intel's known for their failure-prone RAID chips, so I'd rather use the "safer" software option, even if it means the data rate will be a little slower.
When a disk is beginning to fail, you can use cloning software to move the RAID data to a new disk without breaking the array.
