Zyxel NAS542 will allow you to store your data safely in the cloud - even away from home you can rest assured of its safety. Security settings will allow you to cooperate on shared files with others, and the RAID capabilities will ensure the durability of data and warehouse operation - even in case of one of the media failure.


Cloud work

Remote access will allow you to work on files from anywhere in the world. Built-in connectors will allow you to conveniently and at high speed transfer data from other devices to database, as well as share it further thanks to the double Ethernet connector.

What's NAS?

NAS, i.e., the Internet Area Storage (Network Area Storage) stores data like a normal computer, but allows for remote access.

Why does NAS542 have two Ethernet connections?

Dual Ethernet socket in Zyxel NAS542 is used to aggregate the network connection in order to obtain maximum throughput, which on a single socket is limited to 1 Gb/s.
