> Xpenology is a bootloader for Synology’s operating system, called DSM (Disk Station Manager), and is used on their NAS devices. DSM is running on a custom Linux version developed by Synology ... Xpenology creates the possibility to run the Synology DSM on any x86 device like any PC or self-built NAS. So, you can benefit from the powerful multimedia- and cloud features of DSM without buying the hardware NAS from Synology. Many people prefer this because they can pick out their own (more powerful) processor and RAM to handle things like transcoding video.
