ODROID-HC4

ODROID-HC4 HC4-Plus versionincludes OLED Displayand RTC Clock BatteryHC4-Base versiondoes not include OLEDDisplay and RTC ClockBattery, but will beavailable later as anoptional add-on   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. Links to compliance documentation available at the bottom of this listing.
