Oh,You are all cool guys.
I first try to use the neo4 to make a bt server in my school.
But the network server will crashed when I download bt from the websit through ipv6.
And I even can't ping it successful.
When I restart the eth0,it work agian.
But When bt a few minutes,it crashed again.
And I try many ways to find out the reason.
But I don't know why.
So I give up this device.
And I buy a Nano pi M4 for testing if it has the same problem.
In Neo4 with 5v4a,I test the seq speed from sftp to my computer.
The speed is only 50MB, and write speed is only 30MB.
I test it in a ntfs usb3 hdd disk.
the speed when i use the ntfs in my computer or other arm board is always 100MB.
I don't know why.
if it is neo4 has some handware bug or software bug??
all is gone,next I will try use nanopi m4 as a test in bt server, smb server and sftp server
