The ASUSTOR Xpanstor 4 docking station connects via USB 3.2 Gen 2 Type-C and expands the capacity of a compatible NAS. It supports MyArchive for accessing cold-storage drives and scheduling backups. Smart power synchronization helps save energy, while the smart fan monitors the temperature.
It supports hot-swappable drives and multiple volumes, as well as RAID-level migration and RAID capacity expansion. Drives in the expansion unit cannot be combined with NAS drives in the same RAID array.
