This is good if you'll use this as a NAS, since you can use the SATA port . Not as good as Pogo E02 if you're using some other CPU-intensive service because CPU is slower and less RAM.
A cheapest plug is Pogo E02, for a box running all these: DLNA/uPnp ,server, torrent, and Samba. Of course the disk intensive function with USB will be not as fast as SATA, but since you are running more than just NAS, it is OK to compromise.
