Fujitsu MHY2100BH Wide temperature range, Low noise and vibration, High resistance against shock

1.1 Features

(2) Wide temperature range

The disk drive can be used over a wide temperature range (5 °C to 60 °C at DE surface).

(3) Low noise and vibration

In Ready status (while the device is waiting for any commands), the Sound Power level of the disk drives in idle mode is 2.0B [MHY2120BH, MHY2100BH, MHY2080BH, MHY2060BH, MHY2040BH] / 2.4B [MHY2250BH, MHY2200BH, MHY2160BH]. The Sound Pressure level is 22dB [MHY2120BH, MHY2100BH, MHY2080BH, MHY2060BH, MHY2040BH] / 28dB [MHY2250BH, MHY2200BH, MHY2160BH], as measured 0.3 m from the drive in Idle mode.

(4) High resistance against shock

The Load/Unload mechanism is highly resistant against non-operation shock up to 8820 m/s2 (900G).

1.1.3 Interface

(1) Connection to SATA interface

The disk drive has built-in controllers compatible with the SATA interface.

(2) Data buffer

The disk drive uses the 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) Error correction and retry by ECC

If a recoverable error occurs, the disk drive itself attempts error recovery. The ECC has improved buffer error correction for correctable data errors.
