Reliability - We understand the importance of your data, and we are
committed to protecting that data with exceptionally reliable products,
advanced data protection technology and superior customer support.
Cool - Keeping the drive cool enhances reliability. WD continues to develop
new and innovative ways to keep drives cool while they are operating.
Quiet - The technology that Tom's Hardware Guide called "very fast and
nearly silent" is used throughout this family of drives. Our WhisperDrive
technology minimizes noise to levels near the threshold of human hearing. To
cut seek noise, SoftSeek technology streamlines read/write seeking
algorithms, resulting in more efficient operation.
NoTouch ramp load technology - The recording head never touches the disk
media ensuring significantly less wear to the recording head and media as
well as better drive protection in transit. (Available on 120 GB capacities
and above)
IntelliSeek - Calculates optimum seek speeds to lower
power consumption, noise and vibration. (Available on 120 GB capacities and
above)
Compatible - We perform tests on hundreds of systems and a multitude of
platforms in our FIT Lab and Mobile Compatibility Lab to give our customers
confidence that our drives will work in their systems.
