Odroid-HC4 is a mini computer specifically designed to run as a 2-bay Network Attached Storage (NAS). The board came pre-installed with a transparent plastic case in a "Toaster" form factor. It has two SATA slots that you can put in 3.5-inch or 2.5-inch HDD or SSD. These storage drives are not included. Odroid-HC4 is powered by Amlogix S905X3 quad-core processor mated with 4GB of RAM. Odroid-HC4 has a 5.5mm DC barrel jack for power, a Gigabit Ethernet port, a HDMI 2.0 port, a single USB 2.0 port and a UHS-1 compatible micro SD card slot. All connectors are available on the rear side of the case.
