Nixeus Fusion HD... Need to choose HDD

Hi computer-philes!
I finally made a digital source choice of Nixeus Fusion HD network media player. As it comes with no HDD, I need to choose the right one. I did not shop recently for the computer parts, but I would assume that my choice should be between 1 and 2TB, 3.5" SerialATA(just like in the desktop), quiet, fast and R E L I A B L E.
I would try to use a Solid State hard-drive to keep the OS on and to use as a medium to store your "Now Playing" files if you plan on using memory mode. (40-60GB about $69). Keep the rest on SATA II drive.
