Using a dedicated RAID controller (instead of RAID features build on the motherboard itself) will improve your overall performance but you should always consider the corruption problem. Personally I use 4 disks in a RAID 10 configuration on a dedicated RAID controller providing the best performance and recoverability. Other likely configurations would be RAID 5, 6, 50 or 60.
A RAID 0 from the motherboard increases the risk and only provides a modest performance improvement.
Please note that the boot disk has a maximum size of 2 TB this is always a consideration when constructing a RAID array for your OS.
A fast disk for the swap file (and some OS components) is often a better option but be aware that with a lot of memory you might not actually use the swap file at all.
