If the M.2 SSD fails: Since you're planning to install TOS (the operating system) on the M.2 SSD without RAID, if the SSD fails, both the OS and the temporary storage pool (on that SSD) will be lost. However, this should not affect your data stored on the HDD storage pool (especially if it's set up in TRAID), as the data is stored separately on the HDDs.
HDD Pool Access: In the event of an M.2 SSD failure, your data on the HDDs should remain intact, as long as they are part of the separate storage pool. You will need to reinstall TOS on a new M.2 SSD (or another drive), but the HDD storage pool will still be there and accessible, provided it's not dependent on the SSD (which in your case, it sounds like it's not).
Data Backup: It's always wise to have backups for your critical data. For TOS, while it's not typically backed up in the traditional sense, you can back up configurations via the TerraMaster web interface. This will allow you to restore settings (like network settings, user accounts, etc.) but not the OS itself. You could also create a system image of the M.2 SSD, although this can be more complex.
Mitigation Steps:
Consider RAID1 for M.2: This would add redundancy for your TOS installation. If one M.2 fails, the other can take over, preventing a complete loss of the operating system. This would give you peace of mind regarding the failure of the SSD itself.
Backup Your TOS Settings: Even though the OS itself can’t be backed up easily, you can export your configuration settings. This is important in case you need to reinstall TOS on a new drive.
Temporary Storage on SSD: Since you’re planning to use the M.2 SSD for temporary storage, I recommend being cautious with that data. It’s a good idea to back up anything important stored temporarily on the SSD to another location (like an external drive or cloud storage).
