I VACUUM every sunday so that is done already. =/ 

Not sure I have the proper params though since I'm not used to db's but have followed other's "how to's", but these are the lines in my script for that;

${BINARY_PATH}/vacuumdb --analyze --host=localhost --username=postgres --echo --verbose --no-password ${database} | tee -a ${log_pg_optimize}_${database}.log
${BINARY_PATH}/reindexdb --host=localhost --username=postgres --no-password --echo ${database} | tee -a ${log_pg_optimize}_${database}.log

RAID6. Doing disk test I have 1000MB/sec write and 1200MB/sec read.

Okay, I was kind of wrong about 40GB.  That’s the size of your compressed backup files, not the size of your databases.
May be your dbs are “bloated”?
You could try VACUUM FULL on your databases, when there is no other activity.
