Hello, i am a bit confused. I have white labeled drive from WD My Book - WDC WD80EZAZ-11TDBA0

After googling i see what this drive hasn't TLER enabled by default, in Unraid you can do by running some script on startup.

Here in forum i seen that i don't really need TLER as Unraid don't have benefits from this feature

I just want to some confirmation from LimeTech to understand, do we really need TLER on Unraid or NO

Thanks

TLER or Time-Limited Error Recovery is Western Digital's method of improving drive error handling in RAID applications.

But unraid is no RAID... so?

 

Explanation:

Is there any benefit to using TLER / CCTL / ERC drives? Maybe. These features usually come on "Enterprise" grade drives (WD Caviar RE series, Seagate Barracuda ES, ES.2, Samsung Spinpoint F1), which are built to take the constant, hard use of business environments. So investing in these more expensive drives is probably a smart move if your NAS is under constant heavy use. But it will be the more robust drive construction and not TLER / CCTL / ERC that will make your RAID NAS more reliable.

 

...and again - its for a RAID-NAS...

Anyway, i seen all of this. Error recovery can be useful everywhere, and unraid is some sort of next level raid

But no one clearly told what i don't need drive with TLER. 

So its good to know and have answer for a future, because this is actual question for some people who buying and shucking WD enclosure drives.
