Sorry, couldn't help it. RAID has to be configured... With 3 drives you could do RAID 5 which would be your best ensurance for fault tolerance and redundancy... That's most likely what you want if you really need it. I certainly would save the money unless you're a server administrator or running data that simply cannot be lost. Of course, there are other solutions available for such things such as tape drives and backup utilities. They might be cheaper unless you were just trying to gain some experience. 😉
