I hope that they are more reliable then WD's Red has been in the past. One simply needs to look at the many 1 star reviews on New Egg or Amazon to see the problems in reliability. I use WD Blacks in both of my QNAP units a 4 drive raid 5 and a 8 drive raid 6 with almost uncanny reliability all though they are enterprise blacks. The regular WD Blacks I sold when I operated a business were very reliable.
there should be more legal protections for consumers against hard drive failures as well and also legal protections against grey market goods. so many people get burned by having a failing hard drive only to find out their serial number doesnt have a valid warranty. always check your warranty within the return window folks and stick to drives with 5+ year warranties or be very careful with your data on these cheap chinese built garbage drives.
