Hi, we have an older G5 1.6 Ghz tower that we are converting to a server. We will run our storage as a RAID 1 using two WD RE3 1TB drives, then probably put the OS on a separate smaller drive (possibly also on a RAID 1, not sure). So we will have to add to the 2 SATA ports that are on the MB. We are thinking about getting a Highpoint RocketRaid 1742 for this, so we would also get a couple external SATA ports for our backup drives. - So this being our setup, which provides faster theoretical throughput for the storage RAID 1 array - the internal SATA ports, or the SATA ports on the RR 1742 which are attached to the standard PCI slot (not PCI-X)? Thanks. Just trying to figure out which way to install the drives. We prefer maximum performance for the storage drive, as this is mostly all this server will be doing (serving files). Thanks!
