[. . . ] WD Caviar Green ® TM WD Caviar Green Power-saving Hard Drives Cool, quiet, eco-friendly Interface SATA As hard drive capacities increase, the power required to run those drives increases as well. 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. Width/Height 3. 5-inch/1-inch Product Features Reduced power consumption -- WD has reduced power consumption by up to 40 percent compared to standard desktop drives with the combination of WD's IntelliSeekTM, NoTouchTM, and IntelliPowerTM technologies. [. . . ] (2 TB model only) Native Command Queuing (NCQ) -- Server feature for performance in random I/O transaction environments. It aggregates many small random data transfers and allows the disk to reorder the commands in a sequential order for faster access. Perpendicular Magnetic Recording (PMR) -- Employs PMR technology to achieve even greater areal density. Low power spin-up -- WD Caviar Green drives consume less current during startup allowing lower peak loads. Advanced power technology -- Electronic components deliver best-in-class low power consumption for reduced power requirements and increased reliability.

Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1, 048, 576 bytes. As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-IO organization as of the date of this specification sheet. 2 WD hard drive products manufactured and sold worldwide after June 1, 2006, meet or exceed Restriction of Hazardous Substances (RoHS) compliance requirements as mandated by the European Union for electrical and electronic products. The RoHS Directive 2002/95/EC of the European Parliament, which is effective in the EU beginning July 1, 2006, aims to protect human health and the environment by restricting the use of certain hazardous substances in new equipment, and consists of restrictions on lead, mercury, cadmium, and other substances. 3 Controlled unload at ambient condition 4 The term of the limited warranty may vary by region.
