Running WDIDLE.EXE on the drives as soon as you install them will help in that regard. > I was leaning towards the Black drives but now I'm a bit worried about the > TLER lackingness which was a mistake made my previous sysadmin. It was possible to enable TLER with earlier revisions of the drive, but rumors on the tubes seem to imply that the feature has been removed. I think that any of the REx drives would be fine. The 7200 RPM versions are basically the Black drives, and the Green is the GP drive, just with different TLER settings in firmware. Problems that you're having with your current GP drives are likely to manifest with the RE-Green. > What do people already use on their enterprise level NAS's? Any good > Seagates?

There's no way to toggle it on from OpenSolaris (yet) and it doesn't persist through reboot so it's not really ideal. Here's a patch to smartmontools that is supposed to enable it.
