Hi, I have a pretty small database on my home computer (~25Gb). I have three 250Gb HDDs.
My setup was 1 HDD for OS (Windows XP) and the other 2 HDD in RAID 0 for postgre database. Will I see any performance improvement if I instead have 1 HDD for OS, 1 HDD for pg_xlog and 1HDD for the database?
or do you suggest another setup? (I'm not really concerned about the redundancy for the database, that's why I used RAID 0 up till now, but would save some time if the performance difference is small compared to 3 independent disks)
