Processor: 3.20E GHz P4 Prescott Motherboard: Asus P4P800-E Deluxe - 1009 BIOS Memory: 2 Gig Mushkin HP 3200 Video Card(s): Leadtek A6600GT TDH Sound Card: Creative X-FI Fatal1ty FPS running through Creative Inspire 6.1 6700 speakers Harddisk(s): Total 520GB of Storage = Half a Terabyte; 2 x 74GB Western Digital 10k rpm SATA Raptors Striped in RAID 0 2 x 80GB Western Digital SATA Striped in RAID 0 1 X Maxtor 250GB ATA The Mobo has Promise RAID controller chip and ICH5R southbridge RAID. I am making sure that the info I have thus far read about which is faster for what I intend points me to believe that the ICH5R southbridge RAID would be the best place to park 2 shiny new Raptors in RAID 0 for the best speed and performance for the System adn it's general running. Correct? / discuss please. As part of the discussion, mainly orientated to the Raptor Owners or aficionados of them, when setting them up in RAID what are the best sizes to choose when given the Format the RAID drives options? I hit the "Desktop overall performance" option but am not 100% sure that is the best choice for myself as I was unsure about the other choices, any help would be greatly appreciated in the questions or ponderings above and any discussion topic related that proves of interest.
