I am owner of the precursor, and thought ours was a lot better in the technical specifications. But I was taught ... To the details ... The drive bays are no longer with quick, but you have the plates only in a kind of slide and build these can then insert. This carriage is made so thin plastic that this threatens to break quickly. The boot time of the system will take longer than with my other NAS. As for the transmission of up to 100Mbit, I could find no increase for other NAS here. The switch position AUTO is no longer available. In summary, it is a good to mediocre NAS that brings a good performance. Had I not been so convinced of my other NAS, it would have been a another manufacturer with safety. These Buffalo has too much useful to save in this model!
