Hello, everyone. 
How do you store data when you retrieve it with Qubes?
I am a complete novice in this field. Currently, data obtained with Qubes is stored directly on Qubes. However, it is unclear which data storage method offers the highest security.
what I want to ask is a security comparison between laptops (or HDDs) with Qubes and typical NAS or HDDs. (In this case, please assume both have passwords.)
Qubes offers high anonymity regarding data transmission and retrieval. However, I do not know what kind of security Qubes uses to protect the collected data. Of course, we know that Qubes has very strong security against virus attacks via the internet.
However, for example, in a situation where the memory and other components are physically disassembled and the memory can be carefully examined, is there a difference in security between a typical HDD or “NAS” and the Qubes installed in an HDD or laptop? (Or, in that case, would it simply be like the security of equipment with Qubes installed?) ） .
If Qubes’s security is on par with NAS or HDD, I would consider transferring Qubes data directly to those devices. If Qubes’s security is better, I think I’ll create another Qubes and put data there.
I’d appreciate any advice.
