Very good but insufficient RAM and a little blurring

Very good product but 1 GB of RAM is actually insufficient to properly use XBMC: too many delays in the navigation menus. I switched to 8GB the first week after purchase and there is happiness. That boost at all levels.
Negative points:
1) noise. The sound of the hard drives that "scrape" throughout the day, or worse during a movie, can be a bit annoying anyway.
2) the NAS is supplied without remote control. And even if you have or buy a Harmony remote, you will always target the NAS to be sure that your orders are properly executed.
Positive:
The firmware is updated approximately every 2 months.
