I have installed open media vault on my rock64 and I have a sata3 disc drive connected to the usb3 port. I have tried both armbian and ayufan firmwares and the speed of the samba shares is 30 MB/sec. I know that the system can do more as with FTP I get 100MB/sec. I have tried many samba tweaks but nothing changes, is this the max I can expect?
