When you installed the second drive, there were two resyncs needed.
The first one is to resync with the 4 TB volume.
After that there is vertical expansion to the 8 TB volume. A new 4-TB "upper" RAID-1 layer is created on both disks, and that also needs to be synced.
I suspect the vertical expansion is what you saw.
The system is now online, adding to above entries, I only have this new log alert added:
Thu Apr 21 2016 0:40:37 Volume: Volume data is resynced.
So, the full log is:
Thu Apr 21 2016 0:40:37 Volume: Volume data is resynced
Wed Apr 20 2016 16:58:29 Volume: Volume data health changed from Degraded to Redundant. Wed Apr 20 2016 11:15:24 System: ReadyNASOS background service started. Wed Apr 20 2016 11:15:23 Volume: Resyncing started for Volume data. Wed Apr 20 2016 11:15:11 Volume: Volume data is Degraded. Wed Apr 20 2016 11:15:09 Volume: Volume data usage exceeds 95% of size (3.6 TB). Wed Apr 20 2016 10:49:32 System: The system is shutting down. Wed Apr 20 2016 7:00:52 Disk: Disk in channel 2 (Internal) changed state from RESYNC to ONLINE. Wed Apr 20 2016 7:00:51 Volume: Volume data health changed from Degraded to Redundant. Wed Apr 20 2016 7:00:48 Volume: Volume data is resynced. Wed Apr 20 2016 1:00:52 Volume: Volume data is Degraded. Tue Apr 19 2016 22:09:02 System: ReadyNASOS background service started. Tue Apr 19 2016 22:09:00 Volume: Resyncing started for Volume data. Tue Apr 19 2016 22:08:48 Volume: Volume data is Degraded.
So basically, disk 1 took 6h, disk 2 took 6h, system came to redundant and a new resyncing started and took around 8h (NAS used so maybe it explains the extra 2h !)
The last resync did not show in logs, but only in GUI:
System/Overview: Status Healthy, volume resyncing
Why this 3rd resyncing and 6 to 8 extra hours spent + it is not shown in logs, but only in GUI?
What disks were you using before?
2 Seagate NAS Drives of 4TB each, with a healthy state, replaced by 2 Enterprise NAS Drives of 8 TB each
By the way, I had to drill holes in the drive support plate. The Seagate drives have 2 screw holes not at standard place
Every thing is fine now, except that extra resync I still don't get and mainly, that is not shown in email alerts/logs

Thank you for your answer and sorry for the delay to mine!
I just was surprised because no clear description was provided in the logs
maybe this needs to be adressed ?
