My recommendation would be 'primitive ftpd', free from Play Store.
Thanks very much .. Who again mentioned slow ethernet?
First tried with the Internal HDD reaching 60 to 70 Mbyte/sec both read/write speeds which pleasantly surprised me.
Next was curious how USB would do and if USB-2 versus USB-3 really would make a difference. Wow next surprise; on USB-3 it even went further straight up to between 80 to 90 Mbyte /sec which in fact is faster than the NAS I had. There are plenty HDD around which in fact are slower, so if you benchmark be sure to use a fast HDD connected via USB-3 . A full size BD50 uploaded to an USB-3 attached HDD in 10 minutes (=Triple Speed).
This is reaching almost wire-rate Gigabit, which i wouldn't dare to call slow. Shouldn't the title be changed to "Ultra Fast Ethernet"? Also "primitive FTPD" in fact is not that primitive at all with all common options including support for SFTP. It includes a with Q10 pro functional option for auto-start at power-on.
Warning: Don't use it as a background task as it will eat up the entire processor during transfers. Samba Server included does a far better job there (multi streaming).
Bottom line: FTP Server is excellent for uploading content and SAMBA server for streaming local content to any other devices around the house. Fixing the Samba server pending bugs (disk size and free space) it would be perfect. Updated my review accordingly.
