My question: to those of you who have their drives connected to the internal Sata, do you find a great difference in speed compared to USB? I will only be using it for file/print serving and media streaming, but I fear that the bottleneck comes in due to the pro's 700MHz speed, not the interface. Will plugging in via Sata make a difference in media streaming or file sharing? I know WHSE has had great speeds through samba compared to using USB and leming mentions I/O waits with USB, but they are also wizards

tl;dr
>Is it worth buying an enclosure and cable to connect to Sata or just stick with USB?
