immature technology, which was never really redesigned ...

I have a 1TB Network Space since 2008 and have seen so many ups and downs with her.
The transfer rates are usually quite low, even in different networks. If the hard disk the Media Service starts but a database it creates hardly raise, usually there's a timeout. Since the plate is about half full, it stops the media scan never and is accordingly not to use as a media server. Should they respond not at times the support provided me (responding to 24 hours) get reset disk. On / Off switch to On, then back to off and on again. This will reset all settings will be reset and it will work again in the factory settings. This is about once a month unavoidable. The software (Linux based) has been released about 4 times revised, but it has been changed a little chemistry.
User accounts can create, but then not manage and do not delete.
Today, after 6 years of operation, the power supply has been broken, the LED still lit up on the hard drive, but it sounds when you start very weak, and then after a short time altogether.

All in all: clear 6 years with today's technology a long time, but what I had in the time of trouble and I had to apply to waiting times ... I would not buy me one more time and will probably soon be a result of age switch to a different device.
