Fabio,

I'm not sure about the latest and greatest, but a NAS usaully runs 
Linux, with SAMBA handling the networking.  With Paradox, you need to 
enable SMB1 protocol so SAMBA has to run in compatibility mode. I've 
always found a NAS to be slower and have seen a couple installed to 
handle Paradox systems because they had a mix of old computers (XP) and 
new computers (Win10). Their old computers were getting way past their 
use-by date so they wanted a plan where their data would be safe if 
their old computers joined the choir invisible. This is also possible 
with the solution below but they couldn't afford the appropriate server 
and Windows license. The NAS was much cheaper.

It's better to have a Windows10 server with automatic backup acting as a 
server for Paradox files. But don't use this computer for user access. 
Keep in mind that even the latest SSD drives have a limited life, much 
lower (in testing) than the manufacturers say. So I recommend not to use 
them for file servers where a lot of disk writes and deletes occur.
