Is there any particular log that I should concentrate on. i.e. system.log (system log only has todays events).

If you have ssh enabled, you can log into the NAS and run smartctl -x /dev/sdxx
That will show the disk's error log (including UNCs that don't seem to show up other places). https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/Disk-test-running-10-days-already/td-p/1786277
Thanks for the help. The more I think about it, the more it seems to be that the drives are failing (slow directory listings, phantom invisible files appearing, etc) so I've ordered some Seagate Iron Wolf's.
Drive 4 had 131073 Raw Read errors and a few Smart "UNC at LBA" Errors ,
Drive 3 was identical to drive 4, but with 3229 raw read errors.
Drive 2 had zero errors but that Uncorrectable Sector count: 24 is a cause for concern.
Drive 1 is a badass just chugging away leading the pack.
Because each re-sync puts a strain on the drives, the chances you will have another drive fail during re-sync is high with those drives. Make sure you have your backup up to date before you start swapping.
Yes, there's a backup via an External USB HD and Dropbox . Not sure if the backup process will synch or just upload one way to the external HD (Dropbox does remove files from its server if we delete them on the NAS) I'm fairly certain the backups have old folders in them that we deleted a while back. but not worried about that. As long as we have the files stored locally and off-site.
