Write cache is enabled. 

I have a separate sata drive connected to the motherboards sata controller that 
I am using to spool the data.

The only thing that is coming off this raid array is the data to be backed up.  
Writing to that array is done only once per hour and totals about 1gig per day.

I must say I am at a total loss.

Yes if the cache is disabled you will get horrible random write
performance. If this is also the spool drive that can be the reason.
