RouterOS Samba 3.0 or 4.0 Support

Hi, will RouterOS support Samba 3.0/4.0?

The reason I’m asking is that since Samba 3.0, multiple ethernets can automatically aggregate, meaning 2 1000Mbps lines connect to the same machine with 2 NIC, without any LACP support, it will get 2000Mbps bandwidth when it accesses Samba 3.0+ server in the same LAN.

It seems on RouterOS only Samba 1.0 is supported. (Please correct me if I’m wrong)

Second question is for the PCI-e m.2 usage for SSD. Is there anyone using an m.2 SSD here for storage? Just a bit worried about the compatibility here.
