Hi, I'm elasticsearch starter!

I have a curious about performance between hardware spec + elasticsearch setting.

- HDD raid 0 set, replicas=1
- HDD raid 1 set, replicas=0

Which is the better to use elasticsearch ? (if disk fail, speed of recover shard .. )

Thank you for read so mess english XP

I'd prefer the former. "HDD raid 0 set, replicas=1".

Or use of multiple `path.data` without RAID 0 at all might be even better.
