- 1 GB:
- One gigabyte (GB) = one billion bytes; accessible capacity will be less and actual capacity depends on the operating environment
and formatting.
The formatted capacity is an estimate for 512 bytes per sector. - 2 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).
- 3 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. - 4 Bels:
- A unit for indicating noise levels. 1 Bels is equivalent to 10 decibels.
- 5 ºC:
- degree C.
