Thanks to the WhisperDrive technology, you might even forget that you have WD Scorpio Blue hard drive installed in your laptop as it barely makes a sound yet packs lots of power with its 8 MB cache and 5,400 RPM spindle speed. Besides being quiet, the drive also consumes less power as intelligent algorithms optimize its data seeking ability. With 80 GB of storage space, this laptop hard drive gives you sufficient space to store your program files and documents plus some photos and favorite music. In addition, once you have saved your data on this drive, you can be sure it is safe there because the ShockGuard technology protects its platter surfaces and mechanics from shocks. Moreover, the SecurePark feature makes sure the recording head never touches the disk surface, so they both suffer less wear and in turn have better shock tolerance.
