MK1237GSX Toshiba America Information Systems, Inc. (TAIS), Storage Device Division introduces the MK2546GSX 2.5-inch 250GB Hard Disk Drive. The MK2546GSX offers the industries highest areal density per platter, at 200.1 gigabits per square inch. The drive's 5400 RPM motor speed, improves system-level performance by as much as 12 percent when compared to 4200 RPM.

This new drive offers enough capacity for portable video recording and editing, with lower power consumption compared to the traditional 3.5-inch hard disk drives. This functionality provides ideal storage for a range of commercial and consumer notebooks, as well as non-PC applications such as PDAs, printers, copiers, GPS systems and MP3 players. The MK2546GSX incorporates the Serial ATA (SATA) 2.6 interface and is ATA-8 compliant, -supporting high transfer rates of up to 300 megabytes per second.

* One Gigabyte (1 GB) 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 1 GB = 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.
