I guess so! I was speaking with someone on Mastodon today with some WD Reds and they failed at almost exactly the same number of power on hours as mine (~43k hours). Given mine were in a ZFS mirror, they would have had almost identical wear so I suppose we could say they that they're predictable (though mine are the CMR drives which you don't get in the 4T these days and SMR drives are bad for ZFS). If I was to replace them with the same drives I'd have a rough idea when to replace them before they start failing but I'll be buying larger capacities these days so those numbers are probably out the window.
