Absolutely. We only do it with pairs of disks though because RAID0 on any

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

So all your machines just have 2 drives each? Isn't that expensive?

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

Not so much concerned about the performance boost of RAID 0 but rather how
fault tolerant is ES on RAID 0.

So assuming 2 node cluster. If you lose the array on one machine, you still
have the other.
I guess it comes down to what are the chances that multiple RAID0 arrays
fail at the same time on the cluster

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),
have erasing limits - enterprise SSD live longer. When they exceed the
limit, they tend to die abruptly without warning. This is a bit different
from spindle
Raid 0 , don't use 5 as the performance is sucky and ES is i/o intensive.
