I’ve read this topic:
And I found @james_d is using QNAP NAS, the same with me, so I have something to say.
Before judging SQ from internal SSD vs NAS, I’d found a factor DOES affect SQ between internal storage vs network storage: the SMB protocol version of your NAS file service.
What’s the best way to configure my NAS for Roon?
A: Use SMBv3 when possible. Failing that, SMBv2 should also be ok, but do not use smb2 with large mtu as it has known compatibility issues with Roon.
The default setting of QNAP NAS: SMB2.1 should be something similar to the smb2 with large mtu mentioned to be avoid by Roon official.
I’ve setup the NAS for Roon with the above knowledge, so had never compared the difference between SMB protocol versions for a while.
But occasionally I’d experienced the difference between internal storage, SMB2.1 and SMB3 Today.
both the files from internal storage and from NAS via SMB3 are great (still somehow different but not that obvious), and the files from NAS via SMB2.1 is quite poor. The difference is kind of huge.
I guess you might check the file service setting from NAS controlling page.
