Fujitsu gets perpendicular for enterprise and notebooks

Fujitsu has introduced its new 2.5” perpendicular magnetic recording based hard drives. The new MHW2 BH lineup of hard drives is Fujitsu’s first 2.5” drives based on perpendicular magnetic recording technology. This allows Fujitsu to enhance capacity of the MHW2 BH hard drives to a maximum of 160GB. The MHW2 BH lineup will arrive in six models varying in size from 40GB to 160GB with a 5400RPM rotational speed.

Shock resistant and energy efficiency is the highest in the industry according to Fujitsu. All MHW2 BH series of hard drives can withstand up to 300Gs of shock while the hard drive is spinning or 900Gs in a non-operating state. Energy efficiency varies on the size of the hard drive—ranging from 0.015 watts per GB on the 40GB model to 0.0038 watts per GB on the 160GB model.

Fujitsu will also launch a consumer electronics friendly MHW2 AT series too. The MHW2 AT series isn’t based on the MHW2 BH series as it uses traditional longitudinal recording instead of perpendicular magnetic. Nevertheless the MHW2 AT series will have low power consumption and produce 15 decibels of noise, making it ideal for consumer electronics.

Availability of the 40GB, 60GB and 120GB drives are unknown a the moment, though Fujitsu states the 80GB and 160GB models will arrive in October. Pricing has not been announced yet.

I think a normal laptop drive uses around 2.5 watts, so that is pretty amazing.

A normal 7200RPM notebook drive might have a peak power consuption close to 2.5W. I think the peak for 5400RPM notebook drive is about 2W. Their 1.6W, if that's the peak, is closer to the peak of an 4200RPM notebook drive. It's a nice improvement, but nothing revolutionary.

A 0.4W difference in power won't make much of a difference if you are using a hot CPU. If you are concerned about notebook heat and battery life, you are better off going with a notebook with a low voltage or ultra low voltage CPU. The standard voltage notebook CPUs take about 30W, vs 15W or 10W or less with the lower voltage CPUs.
