Adaptability; Interface - Fujitsu MPG3XXXAH Product Manual

(4) 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 8.5 ms (at read).

Adaptability

(1) Power save mode
The power save mode feature for idle operation, stand by and sleep modes makes the disk drive
ideal for applications where power consumption is a factor.
(2) Wide temperature range
The disk drive can be used over a wide temperature range (5°C to 55°C).
(3) Low noise and vibration
In Ready status, the noise of the disk drive is only about 3.7 bels (MPG3204AH, Typical Sound
Power per ISO7779 and ISO9296).

Interface

(1) Connection to interface
With the built-in ATA interface controller, the disk drive can be connected to an ATA interface
of a personal computer.
(2) 2MB data buffer
The disk drive uses a 2MB data buffer to transfer data between the host and the disk media.
In combination with the read-ahead cache system described in item (3) and the write cache
described in item (6), the buffer contributes to efficient I/O processing.
(3) Read-ahead cache system
After the execution of a disk read command, the disk drive automatically reads the subsequent
data block and writes it to the data buffer (read ahead operation). This cache system enables fast
data access. The next disk read command would normally cause another disk access. But, if the
read ahead data corresponds to the data requested by the next read command, the data in the
buffer can be transferred instead.
(4) Master/slave
The disk drive can be connected to ATA interface as daisy chain configuration. Drive 0 is a
master device, drive 1 is a slave device.
