There is clearly more intensive tests on this system, I just want to leave a short impression for buyers who may flirt with this solution here. All in all, the device is really succeeded. Use is titled as "Plastic Bomber", but the workmanship is really good. And looks a lot more sophisticated than some other NAS servers from other vendors. The installation was easy. Fitted sheets, backed up and turned on the device. After a short time the unit was discoverable on the network, the setup function took a by the hand and ran to the installation in the shortest time. About a web interface you could then go into the detail-work and adjust features as desired. Whatever your RAID system, which configuration - everything runs since super through. Also the integration of external USB HDDs was not an issue, up to two can be connected in addition to the storage. Only criticism: There is a power management on and off times. Unfortunately, at the moment is not yet possible broken off to define (eg from 0h -.. 2h turned, then turned from 2h to 8h and cycled from 8h to 0h It can be defined only the switch-on piece ever may improve the situation with a firmware update.
Backup function ran the software made available also been very good in the background (it is always backed up what has changed or been added -> incremental backup). Some plugins allow it to have some nice gadgets run, including BitTorrent Downloader or CMS software on the NAS.
Conclusion: Cheap, fast, reliable, good-looking. Works very well, recommendation!
