Raw I/O bandwidth is not that important when pushing the limits, seek time is far more important when pushing the limits of Squid disk I/O. But I don't think you will see a big speed difference between these, having 4 drives and a lot of RAM. Quite likely CPU will be your first bottleneck assuming everything is reasonably tuned. But I should also say that max load estimations of reverse proxies is a bit hard without knowing the actual workload. Each site is different. Regards Henrik
