Is RAID 1+0 necessary?
We are using Vertica 7.2 community version, 300GB of data on one node.
HPO recommends RAID 1+0.
But I do not envision a problem with write performance which is the point of RAID 0. I am not planning to load, insert or write large amounts of data. I am planning to *query* large amounts of data, but not write a lot. It seems to me that RAID 1 is sufficient.
Is there anything wrong with using RAID 1 instead of 1+0?
