These drives work fine on an RS2416RP+ running DSM 6.2, no issues.
Don't whine they're "surveillance" drives, blah blah. They're hard drives, they work like you expect hard drives to work.
I don't know about DSM 7.x or newer NAS units, but I see no reason why they wouldn't work on them as well.
That's all.
[Update]: Over a year now, no issues whatsoever.
