I don't know if there's any truth to this, but I've read NAS drives also declare themselves "bad" much more readily through SMART, so you replace them sooner.

- moonbug 7y agoThe point is that the fault recovery is delegated up for handling at the array controller level, rather than being processed by the drive.
- wtallis 7y agoNAS drives will more readily return errors for individual IO commands. That's not the same thing as the drive saying it has failed generally, though primitive RAID controllers often treat any IO failure as a whole-drive failure.
- Dylan16807 7y agoIt should just be a setting for whether a drive does 0 retries, 1 retry, 5 seconds of retrying, or longer. Not entirely different models.
- m0zg 7y agoIt probably is a setting. And manufacturers simply make us pay $20-50 more for flipping a bit. I'd be stunned if they have entirely different firmware versions for different products.
