Citation from the datasheet:

WD Caviar Green drives make it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.

Keep in mind, that a computer scientist calculates as follows:

  • 1 KB = 1024 bytes
  • 1 MB = 1024 x 1024 bytes
  • 1 GB = 1024 x 1024 x 1024 bytes

Whereas an HDD manufacturer calculates the capacity of a harddisk as follows:

  • 1 KB = 1000 bytes
  • 1 MB = 1000 x 1000 bytes
  • 1 GB = 1000 x 1000 x 1000 bytes
Therefore software for the maintenance of HDDs often displays a lower capacity than specified by the HDD manufacturer.
