Toshiba's MK2035GSS has more to offer then just 200GB of data storage in a small package.  The Perpendicular Magnetic Recording (PMR) combined with Tunnel Magneto-resistive Recording (TMR) Head Technology makes it a quick drive even with a slower rotation speed resulting in less vibration. The SATA-150 interface and 8MB buffer ensure fast data transfer between the drive and your system.
