ReadyNAS RN20400 Spindown issues, spindown cancelled

I hope someone can help me here before I send this otherwise great NAS back to the supplier.   One big draw for the RN204 was the disk spindown and it just doesnt work. Well I say it doesnt work,...

Hi peachums,

 

Welcome to the community!

 

This seems strange. Let us check it on our end and see if we can reproduce the same problem that you've encountered. Also I would like to know if you have contacted support to create an issue with regard to this feature that won't work properly.

 

 

Kind regards,

    Hi BrianL,

     

    I have raised this as a support case and have also done some further testing.

     

    I put a power meter on the NAS and it seems to be running at 17W when idle and around 35W when being accessed.

     

    Does this suggest that 2 of the 4 disks are always powered up? And would this be the O/S disk + the disk required to provide RAID 5?

     

    I can understand that some O/S tasks may need to access disk from time to time when idle, but all the time would seem excessive.

     

    Maybe its nothing to do with this but thought you might find the test useful.

      Every RAID-5 write requires accessing two drives (and depending on how it is done, could require accessing all four)..  

       

      Since the data is striped across the drives, a sustained read will of course require all drives to be spun up.
