Hitachi announces the Microdrive 3K6, a 3600 rpm, 1.0-inch hard disk drive designed to meet the needs of high-capacity, ultra-portable electronic devices.

With a maximum capacity of 6GB, the drive holds 50 percent more than its predecessor more photos, more music, more data in the same compact size.

The new Microdrive 3K6 delivers a higher data rate for improved performance and is available in an embedded version or as removable storage.

Optimized embedded design
The embedded Microdrive 3K6, configured with a True IDE interface, offers Ultra DMA high speed mode.

This compact, high-capacity Microdrive is a cost-effective, high-performance solution for handheld consumer electronics applications.

6GB maximum capacity in a 1.0-inch hard drive
