6 SCSI Disks RAID 10 x 2 SCSI DISKS RAID1 + 4 SCSI Disks RAID 10

Good afternoon Guys,

I have been reading about RAID for PostgreSQL and some suggestions are:

6 SCSI Disks RAID10 for OS and DB
Or
2 SCSI Disks RAID 1 for OS + 4 SCSI RAID 10 for DB

I know the more spindles you have the better, but if you are going to be reading and writing to the same volume with a single controller, how good that will be?

How do you guys have your RAIDS setup?

Thank you

Renato
