Larger drives in legacy NAS

I have ReadyNAS 516 that has 4TB and 8TB drives in it. I also have an old ReadyNAS Business Pro that has 3TB and 4TB drives in it. Both are working fine.

 

I'm thinking of putting 2 larger drives (8TB) in the 516, replacing 2 4TB drives.

All the drives are on the respective devices approved drive lists.

 

My question is about replacing two older 3TB drives in the BusinessPro with two newer 4TB drives from the 516. However, they are not on the Hard Disk Compatibility List for the BusinessPro. Has anyone tried putting WDC WD4000F9YZ (4TB) drives (approved for the 516) in the BusinessPro?

 

Or any idea if they might work?

 

Thank you.

    Yes, though it is unlikely Blues11 will hit them in just yet, since he'd end up with a 9 TB volume after expansion.  Unlikely he'd have started with < 1 TB.

     

    But I agree that if there's ever a need to do a factory default (for whatever reason), you should consider converting to OS-6.

    Netgear hasn't updated the legacy NAS HCLs for years, so it's not surprising.

     

    These are enterprise-class drives, so they should work fine in your pro.

      Note that there are expansion limits if you are still running RAIDiator 4.2.x, but you can always factory default with the larger drives in place.

       

      If you are doing a factory default, now is the time to consider if switching your Pro to OS6 is right for you.  The big down side is loss of Netgear support, even paid.  But if that's not a concern, there are some big up sides.  One is that if your NAS dies (it is getting long in the tooth), you can move the drives directly to a new OS6 NAS and they'll "just work" -- no hoops to jump through and data to back up.  Then there is the more up to date Linux kernel, newer apps, and an all-around better GUI (IMHO).
