Hopefully, regularly checking the disks' S.M.A.R.T status will help you stay on top of issues caused by those factors.
Also, you shouldn't wait for disks to fail to replace them. HN's disks were used for 4.5 years, which is greater than the typical disk lifetime, in my experience. They should have replaced them sooner, one by one, in anticipation of failure. This would also allow them to stagger their disk purchases to avoid similar manufacturing dates.
I've seen too many dead disks with a perfect SMART. When the numbers go down (or up) and triggers are fired then you are surely need to replace the disk[0], but SMART without warnings just means nothing.
[0] my desktop run for years entirely on the disks removed from the client PCs after a failure. Some of them had a pretty bad SMART, on a couple I needed to move the starting point of the partition a couple GBs further from the sector 0 (otherwise they would stall pretty soon), but overall they worked fine - but I never used them as a reliable storage and I knew I can lose them anytime.
Of course I don't use repurposed drives in the servers.
PS and when I tried to post it I received " We're having some trouble serving your request. Sorry! " Sheesh.
