MHV2 AT Series Catalog
- MHV2040AT : 40GB
- MHV2060AT : 60GB
- MHV2080AT : 80GB
FEATURES
- 120 GB Large capacity :
Massive capacity has been achieved through the enhancement of the head, the media and the record processing technology allowing up to 60GB per disk, maximum 120GB per drive (2 disks) high capacity. - Low power consumption:
The enhancement of spindle motor driving technology and the power reduction of controller circuit enable to minimize by 1.6watt at read operation. It is about 0.4watt or less power consumption compare with our 4,200rpm drives. - Silence: The enhancement of spindle motor driving technology and the stiffness of mechanism have achieved to reduce the acoustic noise of 2.3Bels(1) at idle operation.
- Shock Tolerance:
The enhancement of head holding structure to read and write the data of the media enable in high shock tolerance. The drives withstand up to 300Go-p (duration 2ms) operating shock.

- 1 bels:
- 1bels=10dB. Unit: sound pressure level.
- 2 GB:
- One gigabyte (GB) = one billion bytes; accessible capacity will be less and actual capacity depends on the operating environment and formatting.
- 3 Rank:
- Energy efficiency based on the Law Concerning the Rational Use of Energy indicates the value obtained by dividing power consumption by the storage capacity (Japan only).
- 4 MB:
- One megabyte (MB) as 1,048,576 bytes for Hard Disk Drives' cache size.
Small portion of buffer memory is used for drive firmware control. - 5 ºC:
- degree C.
- 6 Cache:
- The memory to store the data.
- 7 S.M.A.R.T.:
- The function for monitoring the operation in HDD and predicting the failure.
- 8 1.6W:
- Current and power level when the operation (command) that accompanies a transfer of 63 sectors is executed 3 times in 100 ms.
