Raid and tablespaces configuration

Currently my server has two raid controllers both with
5 disks attached::
On raid1: i have the database (RAID 1/0)
on raid2: i have the pg_xlog (RAID 0)

is this the optimal configuration or do i need to make
some changes for better performance....

pg_xlog is basically write-only during normal use, so you might want
to use RAID1 or RAID0+1 rather than RAID5, which has slow write
performance.

You sure there are 5 HD ?

Raid 10 suppose to have 4 HD

Raid 0 suppose to have 2 HD

Total of 6 ??

Any way Raid 0 is fast but give no reability. i prefer raid 1 or 10.
