That could be the case, but maybe I'll have to create a specific thread along the lines of "Anyone having success / problems with WD Green drives?" in order to know a bit more details. There were Mac users also complaining -- see the WDC links in the "Best 1.5TB drives" thread. > I have also followed some TLER related threads here. > I am not sure if there was ever a clear assertion if > consumer drive related Error correction will affect a > ZFS pool or not.

IIRC I think Richard said that he thought that a troublesome non-RAID drive would affect MTTR and not reliability. I.e. you'll have to manually intervene if a consumer drive causes the system to hang, and replace it, whereas the RAID edition drives will probably report the error quickly and then ZFS will rewrite the data elsewhere, and thus maybe not kick the drive. So it sounds preferable to have TLER in operation, if one can find a consumer-priced drive that allows it, or just take the hit and go with whatever non-TLER drive you choose and expect to have to manually intervene if a drive plays up. OK for home user where he is not too affected, but not good for businesses which need to have something recovered quickly. > That all rather points to singular issues with > firmware bugs or similar than to a systematic issue, > doesn't it? I'm not sure.
