Funny. I've used an ARC-1260 in a 10x500gb raid-6 array for several years and it has never gone down. I've RMAd probably 4 drives to WD under warranty. I've also had 2 software 5x1tb raid-5 arrays for about 2 years and they've never even lost a drive. Apparently WD improved their RE drives between the 500gb and 1tb versions, the difference in failure rate is huge.
