Fujitsu today announced that it has developed a new series of 2.5" hard drives specifically designed for "24-hour continuous operation". I doubt there's any need of such "special" drives, but according to Fujitsu such drives are must for if you're pushing your PC to its limit. The MHZ2 BK is designed for use in "demanding environments with high-frequency access, including entry-level servers or storage systems in enterprise IT equipment, and ATMs or POS systems in industrial applications, where reliability is paramount."

The 2.5" drive offers 250GB storage capacity, a rotational speed of 7,200 RPM, and consumes only 2.3W for read and write operations.

Sales of the new MHZ2 BK Series will start at the end of July 2008.
