Although I now replaced by a server with four drives the Zyxel. Yet I was the short time in which the Zyxel was as NAS in service, quite impressed with the performance for the price. Software is so-so. Here and there, missing a few features that you have at the major manufacturers. But the cost sometimes loose the two to three times. The performance of the Zyxel is quite on par with the more expensive units distinct. There is now a newer generation of Zyxel with the same hardware, but other housing. Since the loud fans to have been replaced by a less annoying. Overall, I can only recommend the device for NAS novices. For me, the Zyxel now runs the way to even draw the Week backups of my server / NAS.
