How to Set up FreeNAS Storage Operating System on ODYSSEY – X86J4105

What is FreeNAS?

FreeNAS is a free open-source network-attached storage(NAS) operating system based on FreeBSD and the OpenZFS file system. FreeNAS can be installed on Windows, macOS, Unix clients, and virtualized hosts.

FreeNAS runs on x86-64 hardware so we choose to use our new product ODYSSEY – X86J4105 to demonstrate how to build a personal cloud drive by installing the open-source storage operating system.

ODYSSEY is a series of SBC (Single Board Computer), allowing you to build Edge Computing applications with ease. The ODYSSEY – X86J4105,  based on Intel Celeron J4105, is a Quad-Core 1.5GHz CPU that bursts up to 2.5GHz. It includes all the powerful features of Mini PC such as including an 8GB LPDDR4 RAM, 64GB eMMC Storage(optional), onboard Wi-Fi/BLE, Dual Gigabyte Ethernet Ports, Audio Input and Output, USB Ports, HDMI, SATA Connectors and PCIe, however, within a cost-effective price starting at $188. With eMMC versions, you even have the Windows 10 Enterprise pre-installed!
