Many of these USB3 HDDs have 1 year warranty for a reason. SMART check on a few month old Seagate USB3 disk I have shows it has already exceeded worst case of many parameters! It still works so I can't return it. You can buy 5 year warranty WD Gold or RE for decent prizes and can put together your own disk array. I don't use a separate ZFS intent log on my main fileserver as I don't rely on NFS much (mostly just readonly access). I also don't use a laptops for fileservice as they don't have ECC memory.
