Thanks for your attention. What would you choose for a postgresql installation: 3 disks configured with RAID 0 (in a self replicating SAN) over 10 disks configured with RAID 5 (also in a self replicating SAN) , we have space constraints that prohibit us from choosing RAID 1+0. I've been persuaded to choose RAID 5, because writes and parity computation will be spread over 10 disks compensating write overhead providing a better level of data security.
Do you think it was a good decision? Any comment will be appreciated. Have a good day. -- El genio es 1% inspiración y 99% transpiración. Thomas Alva Edison http://pglearn.blogspot.mx/
