The disk setup is a disaster waiting to happen. Using a single SSD drive for QNAP apps and containers provides no redundancy. If the SSD develops a problem and becomes read only, you lose all that data. You can add a second SSD drive and upgrade the SSD drives to Raid1 but all drive space would now be taken. It appears that QNAP in the video is a TS-462. That unit has 2 NVMe slots. Those should have been used in the initial setup so that apps would be stored there leaving multiple drive bays for expansion
You should do backups as RAID1 is not a replacement for backups, yes if the SSD did develop an issue then I would think it's likely in a RAID environment that the 2nd drive would also become read only. I see your point of view for somethings and that's your opinion. The video is showing a 'basic setup'. The NVMe slots are generally used for Cache drives, not storing apps.
