That is curious, since I could rapidly get data corruption with firmware 
20.00.00.00, yet ran a stress test for about a week with 20.00.04.00 
with no issues. That was with FreeBSD 9.3, but I just updated my test 
system to 10.2, and it has been running the same stress test for 4-5 
hours again with no issues. I don't doubt your experience at all, of 
course, but I wonder what is different?

For what it's worth, my test machine is a Dell R610 with Dell TYVGC HBA 
(unclear whether this is a 9207-8e or 9205-8e), and WD Red drives in a 
Supermicro SC847 chassis.
