Hitachi builds ultra low-power hard drive

Claims to be world's most energy-efficient desktop hard disk drive.

Hitachi has launched what it says is the world's most energy-efficient desktop hard disk drive.

The company said the DeskstarP7K500, available in capacities ranging from 250GB to 500GB, includes a number of power-saving technologies aimed at reducing active and idle power consumption by up to 40 percent over its the previous generation of products.

When idle, the 250GB model uses 3.6W, while versions with 320GB or higher capacities use 4.8W. Hitachi said typical hard drives use around 7W when idle.

Furthermore, the P7K500 has active power requirements to 6.4W and 8.2W for its one- and two-disk models, respectively.

Hitachi said the models also use Hitachi's second-generation perpendicular magnetic recording (PMR) heads and disks, enabling 250GB-per-platter areal density.

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
