How Robust is Storage Spaces?

PCDoc woke up to the sound of an alarm, the alarm from his Highpoint RAID card, which was highlighting an error within Storage Spaces. With an option to repair chkdsk was run:

…it ran a check disk on all three drives and found no errors.  Shortly after that it began a repair process which took many hours to complete.  When it was complete it still did not tell me anything other than it was completed (not much help). 

Had this been a production system, I would not be able to identity which drive in the system is causing the problem.  Even if it flagged a drive as bad, there does seem to be anyway to track that back to a specific controller port or drive location.  Second, the unexplainable reason for the rebuild in the first place.  What caused it and why?  They should tell me something.  Lastly, since this has only been running for a bout 10 days, the robustness of storage spaces is now a big concern to me.  I have never seen this happen in two years of running RAID 24/7.  This might be a fluke, however it throws doubt for me as to how stable and robust this really is.
