Data Transfer:
Copying large files or many files on the NAS or from the NAS carried out at me with a transfer rate of 80 MB / s on average. Stability Problems with data transfer I never had.
Standby:
My box turns completely stress-free when not in use in the standby mode and wakes up even when requested again. The hard drive is idle for a few minutes ausgeschaltet.Mit destroy the hard drive runs constantly as reported elsewhere.
Loss of network connection after prolonged standby or problems when leaving the standby mode after a long time come with me not to.
DLNA:
Works great with my Samsung TV. Fast forward / rewind, skip everything works without a trailer and problems.
My personal conclusion:
Bearing in mind that the price of the NAS which is hardly a pure 4TB hard drive, you can easily see the price-performance ratio.
