@testdasi - 20 years and no bad sectors, lucky. I had an issue with some of the Seagate 1.5TB drives back in the day, but other than that I have been pretty lucky also.. knock on wood. I didn't think it was normal, but wanted to verify since I haven't bought a larger platter drive in awhile (just recently replacing my old 3TB HGST's). After some back and forth with Seagate, they finally RMA'd the drives that failed pre-clear. I guess they didn't want to do the paperwork as they kept stating that 8 blocks is very low and not to worry. Long story short.. all is good here now. All drives are 0 bad sectors.
Side note, on your TR build. Are you running ECC or just DDR4? I've been debating on upgrading my unRAID build to Ryzen/TR, but was waiting on stability.
Thanks all who replied.
