In the meantime, I need to gather some numbers on the current adaptec stuff that we're running. I'm aware of bonnie/bonnie++ and IOZone. bonnie doesn't really seem thorough enough for what we want to test for (random reads/writes), and IOZone forces you to do some ugly contortions in MS Excel to get any decent graphs. We're mainly looking for a controller to pair up with a few Postgres database hosts. We are leaning heavily towards the latest and greatest from 3Ware and Areca. They are SATA, but are getting lots of praise from folks on the postgres-performance list. This is apparently not so much because of the underlying disk technology (SATA vs. SCSI), but because both vendors are just putting much more modern processors on their RAID cards compared to the rather anemic stuff that LSI, Adaptec, et al. use. So what do folks here use to get detailed data on a raid array? Thanks, Charles
