That would work, although I would recommend altering your scheme slightly: use the 18GB array (3x9GB + hot spare, assuming you're doing RAID 5) for /, swap, /tmp, /var, /usr, and then dedicate the 36GB array to /var/mail. This will allow those spindles to occupy themselves with mail and not have to worry about things like log files. (Keep in mind that some software, especially IMAP and webmail apps, also store mail under the user's $HOME, so that may affect your disk layout as well.) > Is this a workable way to do it?

I haven't used 5.2 in production yet, but I have used it on a couple of test systems (and my workstation) without problems. The programs you mentioned all use multiple processes (and/or threads), so the operating system (even 4.x) should be able to distribute them between the CPU's without any trouble.
