I'm having an issue with my sqlservr.exe which is always reading the SBSMonitoring.mdf, around 50MB/sec. I saw that in Reliability and Performance mmc. I don't think my hard drive love it... and it slows down my server. We have a SBS 2008.
I found nothing about it, help me please :) Thanks.
I had the same issue and posted to Microsoft's SBS Community forum. I was directed to Microsoft Knowledge Base article 981939 which seems to have fixed my problem without disabling the monitoring.
The article includes a powershell script to reduce the amount of monitoring data that is kept from 90 days to 30 days and adds some indexes and statistics to the database.
SBS Monitoring looks like a beast. I've found two links for you to look at:
I hope these help. You might want to look at either turning this off, or configuring it to use fewer resources. 50MB/s sounds like your drive is exclusively doing this monitoring.
EDIT: Here's another link. This may be more useful:

If you aren't using the monitoring disable it. It sounds like you are monitoring a ton of stuff. You can also check the database in SQL Server and make sure that it's not set to autoclose the database which would add to the problem.
