I saw in Fry's San Jose ad today they were selling these Serial-ATA/300 drives for $67. They didn't give a model number but scouting around a bit on the web I'm guessing they are a discontinued model. Any inputs on whether these are drives that work well with mdadm RAID? Do they support TLER and otherwise work well? This would just be a home server of some type, nothing industrial. Probably a 3 drive RAID-1 or something like that. Comments?
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).
