If you're talking about 2 disk RAID-1 versus 10 disks RAID-5, those numbers may change. If the drives are integrated into the systems, it's also possible the RAID-1 disks are faster drives than the RAID-5 drives... If you're going to run the DB and web server on the same system with a high percentage of static pages, the SMP system may help out. If you have almost all dynamic content is full of complex DB queries, the P4 would do better based solely on CPU speed. How about RAID-1 on the dual PIII and keep the P4 as a workstation? :-) The PIII is likely up to the task, but it really depends on the type of content (is _everything_ PHP generating dynamic content, every page hitting the DB etc?)
