Toshiba Expands Industry-Leading Automotive Storage Line With 80GB Serial-ATA Hard Disk Drive

High-Capacity SATA HDD Enables Faster Data Transfer Rates and Easier Integration for In-Car Navigation and Infotainment Systems
22 Oct, 2008

TOKYO--Toshiba Corporation today announced its first 2.5-inch hard disk drive (HDD) with a Serial-ATA (SATA) interface for automotive applications, expanding its line of robust and temperature-enhanced storage solutions for in-car navigation and infotainment applications.

The new 80GB HDD (MK8057GSC), Toshiba’s first 2.5-inch hard disk drive (HDD) for automotive applications to offer a SATA interface, complements the company’s existing line of 40GB, 60GB and 80GB capacity Parallel-ATA (PATA) products. Migration to the SATA interface enables automotive system designers to easily integrate the new drive with the latest automotive chip-set design technologies. The SATA storage interface allows automotive designers to reduce signal-line complexity, while supporting faster top-end data transfer rates than PATA-based HDDs.

Toshiba also celebrates a key milestone of shipping more than nine million HDDs for automotive applications, highlighting the strong demand and accelerated adoption of disk-based storage solutions by the automotive industry worldwide. The company commands an 84 percent market share*1 for CY2007 in the automotive HDD segment, according to research firm Techno Systems Research (TSR) Co., Ltd.

Toshiba’s leadership in commercializing automotive HDDs draws from more than 10 years of experience working with leading automotive manufacturers and systems providers to design cost-effective, high-capacity data storage solutions that deliver the extended operating specifications required for the automotive operating environment. Toshiba’s latest model features an operating altitude specification of 5,500 meters and supports an operating temperature range of -30o to 85o Celsius. The new 80GB HDD for automotive applications (MK8057GSC) also can withstand operational shock of 300G, providing a robust and dependable storage solution for automobiles operating through extreme temperatures and terrain.

Mass production of Toshiba's new 80GB SATA HDD for automotive applications will begin in December 2008.

1. Toshiba’s first 2.5-inch HDD for automotive applications to employ a serial ATA interface

The new 80GB HDD for automotive applications (MK8057GSC) adopts the SATA interface for interfacing with high performance CPU, which boosts high speed data transfer rates (1.5Gbps) beyond those achieved by the parallel ATA interface.

2. Environmentally conscious products

(1) Lower CO2 emissions during the product lifecycle

During their lifecycle, the new drives will lower CO2 emissions by approximately 68g a year*2.

(2) RoHS compatible

The new drive complies with the European Union’s RoHS directive for eliminating use of six hazardous substances in electrical and electronic equipment.

(3) The new series meets standards for certification as a stand-out Toshiba ECP

Toshiba promotes an “Excellent ECP” (environmentally conscious products) program to stimulate creation of high value products offering exceptional environmental friendliness. For more information, visit

One Gigabyte (1GB) means 109 = 1,000,000,000 bytes using powers of 10. A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes, and therefore shows less storage capacity. Available storage capacity will also be less if the computer includes one or more pre-installed operating systems, pre-installed software applications or media content. Actual formatted capacity may vary.
