PostgreSQL 9.0.x
When PostgreSQL storage is using a relatively large raid 5 or 6
array is there any value in having your tables distributed across
multiple tablespaces if those tablespaces will exists on the same raid
array? I understand the value if you were to have the tablespaces on
different raid arrays. But what about on the same one?
Not answering your question, but standard advice is not to use RAID 5 or
6, but RAID 10 for databases. Not sure if that still hold if you're
using SSDs.
