[Help] Adventures with the TERRAMASTER F8 SSD Plus

[dgmigdot]

TERRAMASTER F8 SSD Plus 8bay All SSD, 8-Core 16GB DDR5 was purchased on Amazon Germany on 16.10.2025 together with two Silicon Power 4TB UD90 NVMe 4.0 Gen4 PCIe M.2 SSDs.
All devices are new.
It was intended that the device would function as a backup station and media server.
The total cost of the package is over 1000 euros.

From the very beginning, I encountered a problem of unpredictable shutdowns.
The device could run for 5 days without issues or produce 2–3 failures per day, completely randomly.

Contacting support did not yield any results.
Vague one-line responses, suggestions to enable debug mode, send logs, etc.

“Send logs” looks like a multi-stage quest: not only do the logs take up tens of megabytes and naturally don’t fit into an email, but they also have to be uploaded to my own cloud storage and then I have to wait until support staff deign to review them.

I enabled debug mode for 5 days, collected logs, sent a download link for the file—and received no response.
At the moment, debug mode is still enabled and the log size is nearly 700 megabytes.

How it is even possible to analyze such a volume of text data and find anything in it is a mystery to me, but so be it.

After upgrading from TOS 6 to TOS 7, the system behavior did not improve at all.
I hoped that for “Beta” mode there would be some extended logging without debug mode, but no.

I don’t think I am asking for anything extraordinary.
I simply want support to give a clear answer: what is going on?
Is the problem in the device, the drives, the software, or the operating system?

Please investigate and explain!
