Hitachi Travelstar 4K120 Hard Drives

Extending the Concept of Cool

The Travelstar 4K120 extends Hitachi's hard drive leadership with a series of hard drives offering storage capacities of 40GB up to 120GB which set new standards for power efficiency and heat dissipation. The two platter 120GB drive consumes up to 178% less power than other 4200 RPM drives through a combination of Enhanced Adaptive Battery Life Extender (ABLE) and Hitachi Voltage Efficiency Regulator Technology (HiVERT) innovations invented by Hitachi. This directly results in longer battery and service life of the Travelstar drive as well as the host system supported. While lower power is usually associated with reduced performance, Hitachi maintains its high standard for performance with a 16% boost in sustained data throughput from its previous generation 4200 RPM drives, to provide a winning combination of high capacity, cool and quiet operation, performance, as well as superior shock tolerance on a proven platform for quality and reliability.

Enhanced Storage Options

The Travelstar 4K120 is the first 2.5-inch hard drive to utilize the ATA/ATAPI-7 standard as well as the AV Streaming Command Set, trademarked by Hitachi as Smooth Stream Technology. Hitachi introduced Smooth Stream on its 3.5-inch Deskstar 7K400 product line and now incorporates that industry leading expertise in Travelstar drives. When Smooth Stream is enabled, the Travelstar 4K120 offers cooler and quieter operation for challenging A/V environments that require less power, noise or a smaller footprint. Hitachi enhances the storage options available for consumer electronics devices that require high quality audio and video at maximum value with the Travelstar 4K120.
