Well, they're perhaps not great. I bought three and after only about a thousand hours one of them was giving SMART errors, then after about 7,500 hours a second one started doing it too. At that point I replaced both with other makes, copying over with ddrescue (or maybe it was dd_rescue), which worked without any failed sectors, then ran badblocks -w on the Samsungs and the SMART errors went away. The third one of mine is still fine, and the other two are now in a ReadyNAS giving good service. Somebody else on this list recently reported problems with them, though that may have been more controller-related than a real problem with the drives. But yes you can set TLER on them (with a custom-built smartmontools from SVN or the recently-released 5.40). Cheers, John.
