I regard Solaris + Oracle as one of the most reliable combinations for moderate to extreme load, for a system that might well be in operation for five to ten years. If I was going to do FreeBSD, I might look into Postgres instead of MySQL; well, I might look into something else than MySQL under many circumstances. I've gotten some pretty good use out of OpenBase, for another choice. As for the disk configuration, using RAID-5 is one of the worst possible choices for a database; using multiple RAID-1 mirrors or a RAID-10 config would probably do a lot better in terms of performance and reliability. -- -Chuck
