is MikroTik SMB safe enough?

hey guys, i have ccr1009 with routeros v6.47
i want to use MikroTik SMB feature as USB Storage, is it safe enough if i enable it?

SMB itself is not safe enough, but that might be debatable. But: any storage you might attach to CCR (except for SD card) is waaay too sliw to make any sense doing it.
