I've been carrying along these 3TB WD reds for many years now. I finally transitioned my prod dataset off of them earlier this year but wanted to see how long they'll go. 3 drives in a temp dataset (Linux isos) keep going like the Energizer bunny. Who else has some ridiculously long PoH droves still in service?
My prod data is in a raid Z2 array and has 2x off-site backups done nightly. The 3TBs are used in low risk things like temp data storage or my NVR.
