I would probably do one RAID1 for the OS, and then one RAID10 for everything else... but, it really depends on how much load this particular box will be under.

Hi there, I'm a novice in squid world and I would like to know what is the best raid performance for this : HP proliant DL380 2 x SCSI disk 36.4 GB 15K 4 x SCSI disk 72.8 GB 15K I thought RAID 5 but it seems it's not the best solution for this. What do you think ? Thanks Will --
