- 1 GB:
- One gigabyte (GB) = one billion bytes; accessible capacity will be less and actual capacity depends on the operating environment and formatting.
- 2 Gb/s:
- Giga bit per second.
- 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 bels:
- 1bels=10dB. Unit: sound pressure level.
- 6 ºC:
- degree C.
- 7 1.9W:
- Power consumption at SATA 1.5Gb/s.
- 8 MHZ2040BH:
- MHZ2040BH no longer being sold.
- 9 Depth:
- Excludes PCBA(Printed Circuit Board Assembly).
