RouterOS storage

RouterOS detects USB, SATA, NVMe and microSD drives and mounts supported ones automatically. Everything lives in /disk; files appear in /file under the mount point. The base system has the SMB server and DLNA media server; the Storage package (rose-storage in /system/package/print; arm, arm64, x86 and tile) adds SMART, Btrfs and XFS, RAID, rsync, iSCSI, NVMe over TCP, NFS and the SMB client. Enable it with /system/package/enable rose-storage then /system/package/apply-changes (reboots; routeros-install-upgrade). Drives with power loss protection are recommended for reliability.
