Raid1 with three drives will have fault tolerance.  You will have three disks with the same image.  This is triple redundancy.  This could greatly improve select performance.

Having said this, I've used software raid5 and am currently using raid10 implemented from PCI ide cards but have had data loss errors occur with both setups.  I am not sure if the problem is in the drives, the pci cards, or the software raid setup. (Thank goodness that this is my toy computer.) 

However, I've used RAID1 with great success for my OS partitions and haven't had any problems of the last couple of years.
