My Dell R720xd 3.5" has had 9 out of 10 hard drives fail over the last two years, and notably all on the same side of the server. Original Dell Enterprise SAS drives, ventilated room, stable power supply and no vibration or high temperatures. Runs Proxmox with ZFS RAID10 + SSD special device, moderate load and good performance.
I am aware the drives are getting old, but this pattern seems unnatural to me. Any ideas what could be going on, or known problems with this server model? The drive backplane has two sets of power and SAS cables, but they all appear to be properly seated. Is this failure rate just to be expected with older drives?
Btw, Proxmox and ZFS is great - I never lost any data through all of this!
