bit-tech published a review of Raidsonic's Icy Box IB-NAS4220-B network storage device

For SOHO or personal and family use, the Icy Box IB-NAS4220-B is pretty nippy and plentiful for the majority of people who are after just a plain two disk NAS. With 2TB hard disks just released, having a potential of 4TB at your disposal should be enough for all but the most prolific porn data collectors. It's a bit noisy, so in a particularly quiet room you'll certainly notice it is on, but it's no better or worse than the alternatives and it still looks great, works great and for the price we'd certainly opt to get one.
