Fujitsu Limited today announced the development of the MHW2040AC model 2.5-inch hard disk drive (HDD) for use in automotive and various equipment that must operate in harsh environments, ranging from cold climate regions to deserts. The new model will be available on global basis at the end of March, 2007.

In addition to their conventional use in PCs, 2.5-inch HDDs are used for a wide variety of applications, such as automotive and industrial equipment. Maintaining its status as a leader in developing and offering products to meet a wide range of customer needs, Fujitsu is releasing the MHW2040AC, the third generation of its 2.5-inch HDD product line, for use in automotive and other applications under extreme environmental conditions.

It also features best-in-class acoustic noise level of 1.5 bels(2) at idle and low-power consumption, operating at 1.8 watts when reading or writing data. In addition to use in increasingly popular automotive navigation systems, the MHW2040AC is also an ideal option for applications where extreme temperatures have caused difficulty, such as industrial equipment, surveillance cameras, PoS systems and ATMs. It is also RoHS(3) compliant.

Sales Targets
Half a million units in the first year of availability

  1. 40 GB capacity: 40 GB is MHW2040AC’s storage capacity. 1 gigabyte is equivalent to 1,000,000,000 bytes. Usable storage capacity is actually less than this figure. Actual storage capacity may vary depending on the environment and formatting of the customer’s system.
  2. Bel: A unit for indicating noise levels. 1 bel is equivalent to 10 decibels.
  3. Restriction of the use of certain hazardous substances in electrical and electronic equipment: A directive issued by the European Union on February 13, 2003 that set legal regulations for hazardous substances in electrical and electronic equipment to minimize risk to the environment and people in member countries. Based on the directive, as of July 1, 2006, the amount of lead, hexavalent chromium, mercury, cadmium, polybrominated bifenyls (PBB) and polybrominated diphenyl ether (PBDE) is regulated in electrical and electronic equipment for European markets.
