Toshiba, the leader in automotive-grade hard disk
drives, introduces the MKxx50GAC 2.5-inch hard disk
drive. Featuring storage capacities of 40 and 80GB1, the
MKxx50GAC is designed specically for the in-cabin
automotive systems environment, and delivers the
enhanced operating temperature range and operating
altitude range required to meet the operating extremes
of the on-road and o-road environment.
Toshiba pioneered the development of automotive grade
hard disk drives to deliver the robust, cost-eective,
high-capacity storage required for the complex GPS
navigation systems used in the Far East and Europe.
Building on this success, Toshiba works closely with
Tier-1 automotive systems designers to meet the
storage challenges presented by the evolving in-dash
“infotainment” and telematics marketplace. In addition,
Toshiba’s automotive-grade hard disk drives provide
robust storage for in-car computing and for on-the-go
digital communications.

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.
