Presumably your SATA drives are correctly being reported by ZFS as  
corrupting data, and you should do something like replace cables, the  
drives themselves, perhaps try downgrading to SATA-150 rather than  
-300 if you are using the later.  Also consider running a drive  
diagnostic utility from the mfgr (or smartmontools) and doing an  
extended self-test or destructive write surface check.
