Bests & Worsts Reviews from Amazon

I ordered two of these to expand my NAS. I had to install one at a time to allow my Synology to rebuild my volume. Each drive replacement takes about 4 days. Well, the first drive started developing bad sectors after about day 7 on the job and then crashed. I was lucky to have redundancy. Anyway, I swapped it out with the other one and ordered a replacement. I just installed the replacement and hoping they hold strong. I like Seagate and am assuming the failed drive was somehow subject to shock before it got to me. I'm giving only 4 stars bc of the failure. If another one fails, I'll come back and update my review to reflect! 27 Sept Update: So far so good. I just checked the two 10TB Seagate IronWolf drives and both are running smoothly with no bad sectors. They do run about 7 degrees (F) hotter than my 6 other, non He drives but don't know if that's normal or not. About sound-They seem quiet to me, similar to my other 10+ Seagate HDD's! Dec 24 2016 update: the two drives are running 24x7 and without any problems. Jun 13 2017 update: the two drives are running 24x7 and without any problems. I'm about to order a couple more IronWolf drives...
