The advantage of cool & quiet
Heat has a large impact on the overall reliability of a HDD's life over time. It can also lead to increased power consumption, the requirement of additional fans and increased fan operation, increased noise levels and the increased chance of failure. WD Green drives come equipped with WD GreenPower Technology which allows the drive to operate cooler with increased overall reliability.
Power management with performance
Best-in-class power management, reduced heat output, and next-generation technologies such as IntelliSeek offer a perfect balance of performance and power, making WD Green a leader in performance when compared to the competition.
Reliability with an increased lifespan
Quiet acoustics, reduced vibration and advanced 4K HDD formatting makes WD Green a stronger solution when compared to the competition and perfect for PCs and external drive applications.
Capacity storage
Large capacity offerings of up to 2 TBs help expand customer capabilities and application usage of WD Green including primary installations in desktop PCs, as secondary storage in external cases or as reliable backup storage.
Next-generation technology
Reduced power consumption, improved data tracking, and WD GreenPower Technology all help to improve the overall reliability of WD Green making it an efficient solution that lowers your total cost of ownership. NoTouch Ramp Load Technology also protects the drive by ensuring the recording head never touches the disk media, reducing wear and tear to the head and increases drive reliability.
