It meets my expectations.
- Nas for multimedia sharing. Connected to a Livebox Play it appears instantly on the network.
Coupled with a WD TV Live, I streamed my mkv without any worries, even files 20GB :).
By cons, multimedia playback via the decoder TV Livebox Play, it does not play mkv.
- For my Mac Time Machine backups. Noted that the rate for Time Machine backups via WiFi is pretty scrawny. Wired it is much more correct. But is it in the WD My Book Live?
- Personal Cloud easily configured via the management console, which I find well made and ergonomic.
In addition, two iOS apps to allow easy access from mobile terminals.
I add the possibility of data encryption and secure password, which is not a luxury.
My only complaint so transfer rates for Time Machine backups via WiFi really ... Phew!
For the rest, really, that's good :)
Enjoy!
