The 2.5-inch MHZ2 BJ series will spin at 7,200 RPM, and include a 3.0-Gbit/s SATA interface. The drive consumes 2.3 watts while reading and writing, and 0.8 watts while sitting idle. Performance-wise, the drive requires an average seek time of about 10.5 to 12.5 milliseconds.

Just for comparison's sake, an older 32-Gbyte Samsung MCAQE32G5APP-0XA00 (selected mainly because it was ten times smaller in terms of capacity) solid-state drive consumes 0.5 watts while actively reading or writing, and 0.1 watts at idle. Since it's solid state storage, there really isn't measurable latency, as there is no time needed for the head to traverse the media.

Samsung charges $499 for its drive. Fujitsu hasn't announced a price for the MHZ2 BJ series, but a similar 320-Gbyte Toshiba MK3252GSX (that only spins at 5,400 RPM) is priced at $169. So there are your tradeoffs.
