Depending on your requirements, you can install an SSD cache and up to five 14TB HDDs. All the popular RAID formats work as you’d expect, including RAID 0, 1, and 5. Thanks to the 10 gigabit Ethernet port, you can achieve read and write speeds greater than 650MB/s and 670MB/s respectively with mechanical hard drives, and there’s support for over 500 different remote users. This makes it possible to use this NAS as a centralised storage facility for 4K video editing, or other shared media production services.


These dual gigabit network interfaces work alongside the 10 gigabit interface to provide a resilient connection to your network. The ports are for network aggregation and failover, letting you choose between redundant access to your data in case of a network failure, or increased speeds offered by a dual-channel network connection.

You can configure the network interfaces, check the health of your drives, configure a database or web server, and manage user accounts.

    The link to the F2-221 review does not work. It needs to be cut in half to work. You can send me a free copy of this product for doing the work of your editor.
