I have an existing areca 1110 raid card with 2x36gb raptors, 1x 250gb sata hitachi drive and will be aquiring the 320 -2x with scsi drives. Or shall i get a normal host scsi card I am interested to put both in my K8we system. As both are using the PCI-X slot, will it affect the speed of each raid card? Whats the drive configuration that is recommned? I play mainly games, design stuff-cad, 3dmax, listen to music, dvd and every things else My plan setup after reading the nice long articles on pagefile OS - scsi hdd (36gb) Pagefile - scsi hdd (think it is recommended to be as fast as the OS hdd) sata raid - running games Applications/ Programs - scsi hdd (36-74gb)
