So given the built in fault tolerance of Elasticsearch across the cluster
I'm thinking of middle ground like RAID5...

If you want speed, use RAID 0.
I have 4 cheap SSDs on one SAS-2 controller in RAID 0.

Not so much concerened about speed I know that RAID0 will give some
Just curious how tolerant an ES cluster is on RAID 0.

If you have replica > 1, more than one server is allowed to fail.
SSDs, also enterprise versions (you can recognize them by the price tag),
