NV+ slows after 15-20 minutes [SOLVED]

That's great, knowing X-Raid is like Raid 4 helps me understand the logs and configuration of my disks. They are configured as expected because when I got my 4 drives I installed disk 1 first to make sure the NAS worked, then disk 2 and then decided as it took so long to rebuild the array that I cold booted with disks 3 and 4 to save time. At least that's what I think I did.

The messing around with the other versions of firmware was all done on my second Duo. This was primarily done so that I was sure that I could upgrade / downgrade firmware without issue, and much of the firmware updating was down to me trying, unsuccessfully, to get Share Mode security available. What I learned from this process was that 4.1.6, 4.1.7 and 4.1.13 seem solid and reliable. Like some other users I found that 4.1.10 a bit slow & flakey.

Having done the testing on the Duo I was confident that a move to 4.1.13 on the NV+ would be the right thing to do. I now have to get some drives for the spare Duo so I can use that as a backup for my backup :)
