I have no where else to put the data in the meantime (4 TB~)

So the data can't be that important then. Whatever device you use for primary storage if your data is important then you wouldn't just store it on the one device. See e.g. Preventing Catastrophic Data Loss

The first one ended up costing me all of my data because the support engineer whacked the raid config on the NAS while trying to fix other firmware issue.

From a quick browse through your cases I can't find any record of that. What's the case number? Did you follow up with support after that problem occurred?

It does sound highly unlikely that a problem like that would be a result of our intervention but you would have agreed that it is your responsibility to backup any important files before we remotely accessed your system. Any brand would require a similar agreement. If you look at the warranty terms for other brands (e.g. the one you mentioned) they also insist that it is the end user's responsibility to make sure that there is a backup in place.

I do recall personally getting support to fix the app uninstallation issue on your system when you ran into that but I see no mention of any data loss in that case.

I should have a resonable expectation of data security and stability with 'tested' builds of the NAS firmware.

If you've lost data it's highly unlikely to be caused by a firmware release. There would be other factors at play and even then a data recovery contract would usually lead to at least some data being recoverable.

"Data security" is achieved by having a large number of backups stored at different locations. Even then you are trying to minimise risk of data loss. This is as true for a business spending several thousand each on servers as it is for a home user using a NAS in the home. RAID is great and redundant RAID levels help protect against one (or for some levels two) disk failure, but it is not a replacement for backing up your data.

It's unfortunate when issues are encountered but you will find that this happens with all brands. One of the tech giants recently released a firmware update that bricked some of their devices. Their QA budget would be huge and yet they still missed a critical issue.
