The device does what it should. The device I imagined simple. The change the RAID level of RAID 1 (default by default) to RAID 0 I found awkward. When starting up the NAS, there are sometimes no connection that is then due at the 2nd boot again available. But actually a NAS runs constantly so that this misconduct does not really count. Once it's going, it is stable. The performance is good, except for a USB 3.0 external HDD directly eingestöpselten. Therefore, a total of 3 out of 5 stars from me, and in terms of the price / performance ratio is a strong buy recommendation.
