<How often will data rates like these ever be an issue, given the much slower disc head seek times?> Traffic is bursty. Hard drives have buffers ranging in sizes from 256K to 1MB (educated guesses). Once the buffers are full, the SCSI controller dumps the data onto the PCI bus in burst transfer lengths. Now imagine six hard drives bursting at scattered moments, along with five network cards who also compete for PCI bandwidth. Ideally, each device will burst data onto the bus separately and everyone will be happy. Yet with that many bandwidth-hungry devices, there will be just way too many times when PCI bus contention becomes a serious bottleneck. That's not something I would want in a server that costs $10,000 at the very least. Maybe $4,000 if I'm really strapped for cash and I want to run nothing but Linux and other "freeware" on it, and if this server isn't very mission-critical. Tenchusatsu
