Not certain if this was mentioned. While WDC WD20EARS drives can be used in an RAID array, WD recommends using there RAID capable drives in an enterprise environment. I tried using same drives in a simple RAID-1 array and had serious performance issues (sync taking a week) and stalls when writing to disk. Are you using the stock firmware on these drives?
