UGREEN NASync Series - Owners Thread

Had some shenanigans with my two M.2 drives. They were each setup as their own simple volume.

A couple of months ago I noticed my backup script was showing an error. I logged into the NAS and noticed one of the M.2 volumes had vanished. I checked the storage section and just one M.2. Oh well, i guess it died. Neither drive had been used hard, but they both had a lot of power on time, so meh.

A few weeks ago I get a notification that one of my volumes was corrupt. It didn't give me information on which volume or how it was corrupt. A few days later the remaining M.2 volume vanished. I logged into the NAS and checked the storage section to see the volume had gone, but the drive was still there. Ok, I guess that was the corrupt volume. I create a new simple volume on the M.2 and it's back up and running.

What I didn't notice at the time is this was the drive I thought died a couple of months ago. It's back from the dead, while the drive that was working is now MIA. WTF!

A few days after that I get a notification that there's an update for the NAS' OS. I update and reboot the NAS and the missing drive reappears.

Now both are working fine. ¯\_(ツ)_/¯
 
I've just bought a Ugreen 4800 Pro & need a little advice from other users.

I bought this NAS for my Emby streaming as my Synology DS918+ is getting a little long in the tooth. The new Synology NAS units have dropped support for Hardware Transcoding, hence the move away from them.

One thing that really concerns me is how the OS is stored seperate from the main raid volume on a single SSD. Is this not a potential single point of failure? I would prefer the OS has the same redundancy as the data, like on my old Synology NAS. Is there a way to set it up like the DS918+, where everything is stored on the RAID 5 array I've created? Data security is paramount to me as I've spent thousands of hours working on getting my Emby to be where is today.

Thanks in advance for any help.
