On a Sil SATA 3114 controller:
/dev/sda OS + Swap
/dev/sdb /var with pg_xlog

On the 3Ware 9500S-8, 5 disk array:
/dev/sdc with the database (and very safe, my MP3 collection ;-))

As I wrote in one of my posts to Michael, I suspect that the card is not handling the amount of write operations as
wellas I expected. I wonder if anyone else sees the same characteristics with this kind of card.
