The disk drive supports an external data rate 3.0 Gbps (300 MB/s) (Serial-ATA Generation-2) or 1.5 Gbps (150 MB/s) (Serial-ATA Generation-1) by each model. And the disk drive realizes a high performance by high-speed transfer rate combined with Native Command Queuing (NCQ). (5) Average positioning time Use of a rotary voice coil motor in the head positioning mechanism greatly increases the positioning speed. The average positioning time is 12.0 ms (at read). 1.1.2 Adaptability (1) Power save mode The disk drive is ideal for applications since it supports the power save mode function that works in each of the Idle, Standby, and Sleep modes and has the Partial and Slumber interface power management functions. And automatically power down by APM function makes the disk drive ideal for mobile use where power consumption is a factor. 1-2 C141-E293
