ReadyNAS 102 OS Update and Disk Replacement

The firmware does need to be upgraded to 6.5.2 first.

The first thing I suggest is making a backup of your data.

If you do have a full backup, then I'd suggest starting fresh.  There has been some tuning to the BTRFS file system over the years, which does improve performance.  But you need to do a factory default to get that boost.  Remove both disks, and insert one of the new ones.  Update to 6.5.2, then 6.10.3, and then do a factory default.  After that hot-insert the second new disk, reinstall your apps, and reload the data from backup.

If you prefer proceding incrementally, then start with the disks - because one of them might be failing. Hot-swap the one with the ATA errors first, and wait for resync to complete.  Then do the the second and wait for the volume to fully expand. Then address the firmware.  

You can find the firmware you need here:

• https://kb.netgear.com/000061727/ReadyNAS-OS-6-Software-Version-6-10-3

Note that you will lose the AntiVirus feature.  Current versions require more resources than available on the RN102.

I obviously need to upgrade from 6.5.1, but the NAS doesn't find any updates when I select "Check For Updates"

Perhaps also check your network settings on the NAS and make sure that there is a DNS server configured.

I have purchased 2 new 4TB disks to replace the existing ones,

If you purchased desktop drives, I suggest exchanging them for NAS-purposed - several models have switched over to SMR in recent years which won't work very well in your NAS.

Similarly, avoid the WD40EFAX, as it is also SMR.  Go with the WD40EFRX instead (or the Seagate Ironwolf).

Enterprise class is of course another option, but IMO are overkill for an RN100 NAS.  Your performance is limited by the CPU, not the disks.
