(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/s

 (900G). 

 

(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.
