WD Green Hard Drives in DAS/SAS enclosures

Headsup to anyone using the WD greens in a DAS/SAS enclosure (freenas/illumos with MPT controllers come to mind), you should enable SSC with a jumper at the back of the drive. For some strange reason, it stops (UDMA errors on BSD) and drive cache sync errors on illumos, which screw the SAS bus up with resets popping the drives out of the pools.
