Once it works so it is OK but not more.
There are certainly a lot of others that are just as good or better for the same money.
Had it not been that I got it at a really good price, I would have probably been looking forward.
Run with latest FW and have a router that should not limit the speed somewhat significantly.
The interface is not the prettiest or easiest to use.
Lacks some features (HD to hibernate among others)
Both read and write speed could have been better.
The media server seems to hang sometimes requiring a reboot. Rebooting should be done from the web interface which is slow and requires a computer.
I mostly run it as a media server and do not mess the media server so I have not had any problems to stream either 1080p or anything else I tested.
However, it seems that every now and then to hang requiring a reboot as well have to go through the web interface and also takes a while before it is up'n running again.
