I had read some tuning guide, it recomment not use RAID 5. So Raid 5 is bestter than 3 disk independent or not.
Here is my pgbench -h %HOST% -p 5433 -U postgres -c 10 -T 1800 -s 10 pgbench
pgbench -h 127.0.0.1 -p 5433 -U postgres -c 10 -T 1800 -s 10 pgbench
Scale option ignored, using pgbench_branches table count = 10
starting vacuum...end.
transaction type: TPC-B (sort of)
scaling factor: 10
query mode: simple
number of clients: 10
number of threads: 1
duration: 1800 s
number of transactions actually processed: 775366
tps = 430.736191 (including connections establishing)
tps = 430.780400 (excluding connections establishing)
Sorry for my English.
