Thanks to both of you for your replies.
I think the idea of internal drive is cool and as long as they make it good in terms of performance, this can be a good NAS solution for home use. Maybe D-link is not paying much attention to it? if not, well that's too bad. The router's box design is terrible and they need a good designer with good quality control. I received one with top cover out of sync and LCD control won't work.
I read somewhere, there h/w version B of this router. Does anyone know what's the difference between A and B version?
Thanks
