The MHW2160BH (160GB) is applied Perpendicular Magnetic Recording (PMR) technology.
The MHW2080BH has PMR technology model and Longitudinal Magnetic Recording (LMR) technology model.
The other capacity products are applied LMR technology.
Specifications are subject to change without notice.
- 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 d rank:
- In case of LMR model, the Energy Efficiency rank is e. (LMR : Longitudinal Magnetic Recording)
