The iron wolf/iron wolf pro are physically different. Both include vibration sensors (vibrations from large numbers of drives can be a killer in NASes) and presumably firmware to slightly adjust spin rates to keep them from all generating the same pattern and making it worse. The IW Pro also has its spindle attached top and bottom instead of on just one end which makes it much less sensitive to vibration problems.
Thanks for sharp eyes. Looked at a wrong spec when writing. All SkyHawks are rated for 180 TB/year. Meanwhile SkyHawk AIs are rated for 550 TB/year. Fixed.
I wonder how reliable these new Seagate HDDs are. I got burned twice by two dying Seagates a couple years ago and I've been buying WD mainly which so far in my experience have worked faithfully.
I have been and continue for now to use HGST He8 and He10 drives, but will certainly consider the Iron Wolf Pro drives as data starts coming out from 24/7 storage users like Backblaze.
Years ago I had a few consumer Seagate drives die, but that was then and this was now and anecdotes are not reliable indicators and neither are one or two drives from a long time ago.

Am I the only one who finds it ironic that this article posted a day after Ganesh reviewed on the of the 3 drives.https://www.anandtech.com/show/13340/seagate-barra...

"Seagate rates Skyhawk HDDs for 550 TB/year workloads."But the table you provide only says 180TB/year. Which one is it?

I like how the only difference between these four drives is the firmware and a wide price gap for said firmwares...DanNeely - Wednesday, September 12, 2018 - link

The news story covers the whole stack, whereas the article covers one of the drives.s.yu - Wednesday, September 12, 2018 - link
I wonder if there's any impact resistance, like if my drive falls off my desk would the spindle immediately disengage before impact.milkywayer - Thursday, September 13, 2018 - link
