Asus Lockerstor AS6704T V2 NAS, 4 bays, Intel Celeron N5105, 4 GB DDR4

Four bays let you start with, for example, two drives and add more as your data grows. You choose the drives yourself to match the capacity you need, because neither the product name nor the manufacturer data mentions drives or capacity. The manufacturer does not state a maximum supported capacity either.

Celeron is Intel's entry-level processor line used in compact devices that run continuously. In a NAS, the processor handles file sharing, backups and background services, so the computers on your network do not have to do that work themselves. The manufacturer data contains no further processor details.

The 4 GB of DDR4 memory serves the storage operating system and its services, letting shared folders, incoming backups and a media library run at the same time. Whether the memory can be expanded later is not stated in the manufacturer data, so check the Asus documentation before planning heavier additional services.

The Lockerstor AS6704T V2 is an upright tower rather than a rack-mounted unit. It can sit on a shelf, a desk or in a cabinet corner near your router, where a network cable is easy to run. All four drives live in one enclosure, so separate external drives no longer clutter the desk.

Families who want to collect photos and videos from every device in one place; small offices that need a shared folder and computer backups; home users who have outgrown external drives; and anyone who wants four-bay storage whose capacity is set by their own choice of drives.
