See the Not Included section below for additional items needed and/or recommended for operation

The ODROID-HC4 is a mini PC with a dual SATA drive dock which makes an affordable solution for a Do-It-Yourself Network Attached Storage (NAS) server. This server centralizes data and enables users to share and stream multimedia files to phones, tablets and other devices on a network. Ideal for workgroups, families, and single users. A wide variety of software is available to tailor the ODROID-HC4 to your specific needs. Upgrade the storage capacity of this server with one or two larger HDD/SSD. The HC4 is built with two high performance SATA port and a Gigabit Ethernet port, to build a faster network storage device, and also supports RAID configurations. The HC4 is designed to hold 2x 2.5 inch HDD/SSDs or 3.5inch HDDs in any combination.

The HC4 is based on the very powerful Amlogic S905X3 chip, just like the ODROID-C4. It can run Samba, FTP, NFS, SSH, NGINX, Apache, SQL, Docker, WordPress and other server software smoothly with full Linux distributions like Ubuntu, Debian, Arch and OMV.
