Hi, i don't know much about hard disks and raid controllers but often there is some discussion about which raid controller rocks and which sucks. my hosting company offers me a raid 10 with 4 serial-ata disks. They will use a "3ware 4-Port-RAID-Controller 9500S" More than 4 disks are not possible. Most operations and all time-critical operations are read-only using a lot of indices. My partioning plans are like this: disk 1: OS, tablespace disk 2: indices, WAL, Logfiles - Does my partitioning make sense? - I want to know if 3ware 9500 S is recommended or if its one of those controllers which sucks. kind regards, janning
