General Description

(16)Large capacity

A large capacity can be obtained from the HDDs by dividing all cylinders into several partitions and changing the recording density on each partition (constant density recording). The disk subsystem with large capacity can be constructed in the good space efficiency.

(17)Start/Stop of spindle motor

Using the SAS primitive or the SCSI command, the host system can start and stop the spindle motor.

(18)Diagnosis

The HDDs have a diagnostic capability which checks internal controller functions and HDD operations. Also, for early detection of and recovery from the errors on the disk, the HDD has a function for periodically implementing a full scan of the disk.

(19)Low power consumption

By using highly integrated LSI components, the power consumption of the HDDs is very low, and this enables the unit to be used in wide range of environmental conditions.

(20)Low acoustic noise

The acoustic noise level is low; approx. 2.9 Bels at Idle. This makes it ideal for office use.

(21)Microcode downloading

The HDDs implement the microcode download feature. This feature easily achieves maintenance and function enhancement of the HDDs.
