Any comments?  Suggestions for other RAID controllers?

I have twin dual opteron, 4GB RAM, LSI MegaRAID-2X cards with 8 disks ([EMAIL PROTECTED] system+pg_xlog, [EMAIL PROTECTED] data) running FreeBSD 5.4-RELEASE.

Works just perfectly fine under some very heavy insert/update/delete load. Database + indexes hovers at about 50Gb.

I don't use the adaptec controllers because they don't support FreeBSD well (and vice versa) and the management tools are not there for FreeBSD in a supported fashion like they are for LSI.
