I am not using RAID. I will have 4 HDs and 2Opt.\nI would put 2 HDs and 2 Opts on the EIDE controler.\nHowever, I have and extra Promis ATA 100 PCI card from my old PC. So, I\ncould install only the 2 OPTs on the card. Other devices will be, a SCSI\ncard for my scanners, a tele Modem. I will also have 2 more HDs on the MoBo\nPromise Controller.\n\nIf I use the PCI card Promise controler will there be a speed advantage?\nWill there be a resource problem?
