Yes it probably would create i/o bottlenecks to some degree. This is why using a multi-disc
hardware raid-array with a BBU is so popular. There is alot of discussion of this on the
preformance list. A raid 10 array will allow for the increase I/O through-put.
I have seen advice to the effect that hand partioning your database accross muliple drives many
not produce desirable results and is a bad idea. It seems and it is hard to balance tuple growth
evenly across all of the drives. Also most of your data writes are on one table, then you are
limited to the i/o bandwidth of one drive anyway.
However, a better/safer way to relieve i/o conjestion is to move your wal-archieve directory to
another drive.
