ReadyNAS 31600 HCL (Hardware Compatibility List). exact URL?

I am looking for the *exact URL* that shows the HCL of disks for a Netgear ReadyNAS, a sticker on the backside says: "RN31600". I know it is no longer supported, but the list (HCL) with compatible hard drives should still exist.

  • The HCL has not been updated in YEARS and is best simply ignored.  Any NAS-purposed or Enterprise drives work well.  WD Red Plus or Pro and Seagate Ironwolf are popular and excellent choices.  DO NOT get a plain "WD Red".  Though WD claims they are NAS-purposed, they are SMR drives and not at all suited for RAID.  Avoid desktop drives, too, as most are also SMR.

  • O.K. Thanks.

     

    What about using SSD Disks, when starting with a diskless Readynas-31600.

    Are for example SSD disk Samsung 860 EVO, 2 TB any good for NAS?

     

    How do I recognize that a SSD is good for NAS RAID use?

    It looks like they took it down.  Which IMO is a good thing, since it hadn't been updated in years, so not useful.

     

    WD Red Plus, Seagate Ironwolf, Toshiba N300 are all NAS-purposed drives that will work well with the RN316.  So will any enterprise class SATA drive (but not SAS).  Avoid desktop class drives, since almost all are SMR - which don't handle RAID very well.  You can use a mix of drives in the NAS with no issues.  You do want to make sure the replacement drive is at least the same size as the one you are replacing.  Best to get one that is at least same size as the largest disk in the array.

     

    There is no known size limit for OS-6 ReadyNAS systems.  That said, really large drives do use more power, and will take a lot longer to sync.
