The N4100PRO can be had at a street price of around $379, which is certainly more reasonable than the other units, but units such as the Synology DS408 come with a more powerful processor and double the memory for roughly $120 more. The N4100PRO is a solid unit with features to match or exceed others out there on the market at a good price, just don't expect it to set any land speed records with its data transfer rates, which I think is the real killer here.
