My friend had bad luck with GoHardDrives. I bought from 6 HGST 12TB drives from a different seller a couple of years ago and it’s been pretty decent. I had 1 fail within the year and got a refund with no effort. A second failed shortly after, outside of warranty. Accounting for the 1 I paid to replace I still came in below cost of new. Plus I now have a very healthy mix of power on hours and models with RAIDZ2 which I feel good about.
