Fujitsu has announced the newest addition to its 2.5-inch hard disk drives (HDD) - its new series MHZ2 BT 2.5-inch 500GB 4200RPM SATA HDDs.
Touted as fourth-generation high-capacity 4200RPM SATA drives, the MHZ2 BT series drives require only 1.8 W of power for read and write operations, thus getting ranked as amongst the most power-efficient drives in their class.
With global spread of digital broadcasts and Internet-based video distribution, along with increased storage requirements, there is an increasing need for high-capacity hard disk drives that can handle high-volume data storage. Meanwhile, with growing concerns over global warming and other environmental issues, there is simultaneously, increasing demand for hard disk drives that consume lesser power. Addressing these concerns, the new HDDs spin at speeds of up to 4200 RPM, offering improved power efficiency, and running quieter than older 2.5-inch SATA drives. More importantly, they do not require built-in fans.
The new series will be available in 400GB and 500GB capacities, and can be used in PCs, Digital Video Recorders (DVRs), Set Top Boxes (STB), and external hard disk drives. The series supports Serial ATA 3.0 Gb/s interface for high-speed data transfers. It will start shipping by end of May 2008. Apart from Fujitsu, Hitachi has announced new 2.5-inch 5400 RPM notebook hard drives with maximum available capacity of 320GB.
The Travelstar 5K320 hard drives feature optional Bulk Data Encryption and altitude-sensing Thermal Fly-height Control, which is fourth generation perpendicular magnetic recording (PMR) head technology for increased data security. The SATA interface of the hard drives provides a faster 3Gb/s data transfer rate, allowing them to be used in a wide variety of applications. Like the Fujitsu drives, the Hitachi drives too consume 1.8W of power when reading and writing.
The Hitachi Travelstar 5K320 series is available in single or dual-platter configurations, in capacities ranging from 80GB to 320GB.
