There have been a few recent discussions on the pg-performance mailing list that touched on RAID-50. I'm sorry, but I don't remember the conclusions (if there were any). I'd suggest a peek at the archives. Are you researching this for Postgresql Solaris? I would certainly appreciate hearing about any of your findings, especially if this is for a PG/Solaris/LVM combination. Regards, Michael
