I have same problem on ASUS RS120 with Seagate ST3250820AS/3.AAC drives 
(disk loses, system reboots, slow read/write speed), but I think this is 
drive problem - all drives has high Reallocated_Sector_Ct value in SMART 
(above 130 reallocated sectors after few weeks, some drives has more 
then 100 after few days).
Please let me now, if you also have nonzero Reallocated_Sector_Ct in 
smartctl -A output.
I will test those servers with brand new Samsung drives, hope that it helps.
