Just loaded readynas 516 with these drives (ST8000AS0002)
I just wanted to let people know that the readynas 516 is working just fine so far with Seagate ST8000AS0002 8TB hard drives. I so far have populated it with 4 of them and it has had no problems. Once...

And of course the footnote:
I think the lower workload spec is the key here; AFAIK it is a new specification for Seagate. I haven't seen it on other datasheets, so I'm thinking they created it for this particular drive line. So it could have quite a bit of analysis/thought behind it.
180 TB per year is probably fine for many users. But if you want to stay within it, you will need to be thoughtful on disk maintenance (disk tests, defrag, balance, and scrub). Just installing them one at a time (as the OP did) puts 40-48 TB of workload on the first drive installed (depending on what else is in the system when the first drive is added). Each scrub adds another 8TB of workload for each drive. RAID of course increases the I/O for writing (bad for workload), but it also spreads both the reads and writes are evenly across all the drives (which could be good).
The reliability comment is interesting, though of course it might not have anything behind it.
Archive HDDs are not intended for surveillance or NAS applications, and you may experience lower performance in these environments. For these applications, Seagate NAS HDDs and Seagate Surveillance HDDs are suggested for better performance and reliability.
