"An impressive box of hardware let down by an unproven and immature software ecosystem."
The dual 10GbE ports allow for a theoretical maximum network speed of 2,500 MB/s, but achieving that requires a full 10-gigabit network infrastructure, which most homes and small offices do not have.
This is for the hardware enthusiast or prosumer who wants maximum CPU and I/O performance for the dollar, and is willing to accept the risks and limitations of a first-generation software platform. Video editors needing direct-attached Thunderbolt speeds and NAS network access in one box may find value here.
Anyone whose primary concern is the absolute, long-term safety and stability of their data should avoid this until the software has a multi-year track record. Users seeking a simple, set-it-and-forget-it appliance with a rich app ecosystem will be better served by a similarly priced Synology.
