I’ve not heard any out-and-out horror stories, but I’ve got no first hand experience.
I’m planning on picking up 3x manufacturer recertified 18TB drives from SPD when money allows, but for now I’m running 6x ancient (minimum 4 years old) 3TB WD Reds in RAID 6. I keep a close eye on SMART stats, and can pick up a replacement within a day if something starts to look iffy. My plan is to treat the 18TBs the same; hard drives are consumables, they wear out over time, and you have to be ready to replace them when they do
