Safe operating temperature for WD Red 6TB


Hello everyone,

I would like to know what is safe, daily operating temperature for WD Red 6TB (WD60EFRX)? I know that the datasheet says 0-60’C, but I found somewhere on the Internet that it shouldn’t go above 45’C, because the failure rate then doubles. The drives are in my NAS which is operating 24/7 and I would be grateful if someone from WD could address that more or less officially.




Hello klu16,

I would suggest that you can believe on the data that is provided on the datasheet as these drives go through various test before they are sold in the market.


Hi Neo33,

Thanks for your response. I based my question on this article:

But I’m not sure what kind of drives were taken into account there and if WD Reds could endure more with higher temps, if they are NAS drives. I just want my drives to last as long as possible.


60º is the max allowed temp for most electronic devices (graphic cards can go over 100º) but hard drives use aluminium parts and you know what happens when you heat them up ?
my advise is 35º during summer days is perfect, no more.
45º is a lot to me, if you touch the upper cover it’s really warm.


Here are my current temps.

Under high load one of the disks sometimes reaches max. 39-40’C. Ambient temp is 22-23’C.
