The main point is that, whatever RAID you use, you need matching drives.

They don't need to be fro the same manufacturer, in fact there is a school of thought that says they should be from different manufacturers. From time to time, any manufacturer can produce a batch with a higher failure rate, you don't want a RAID full of these, mixing makes can reduce the chance of multiple drive failures.
