2.5-Inch Automotive-Grade Hard Disk Drive
Designed Specifically for the In-cabin
Automotive Systems Environment
Toshiba, the leader in automotive-grade hard disk
drives, introduces the MK8050GAC 2.5-inch 80GB
Hard Disk Drive. Designed specifically for the in-cabin
automotive systems environment, the MK8050GAC
delivers the enhanced storage capacity, operating
temperature range and operating altitude range required
to meet the operating extremes of the on-road and offroad environment.
Toshiba pioneered the development of automotive grade
hard disk drives to deliver the robust, cost-effective,
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 onthe-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.
