Designed with top-of-the-line notebook computers in mind, this high
performance drive delivers the capacity and speed needed to supercharge
a notebook PC without compromising battery life or quiet acoustics.
Features like these also make this drive an outstanding option for
compact desktops, external hard drives, gaming systems, and blade
servers.
Key FeaturesDesktop-class performance for notebook computers
- With 5400 RPM spin speed, 8 MB cache, and capacities up to 80 GB,
these drives enable you to have the best of both worlds: the capacity
and performance of a desktop PC with the convenience and portability of
a notebook.
Massive capacity - WDs 80 GB 2.5-inch drives offer
huge capacity for space-hungry operating systems like Windows Vista,
with plenty of room left over for photos, music, and video.
Low power consumption -
With technologies like IntelliSeek, which calculates optimum seek speeds to lower power consumption
and SecurePark, which reduces power by parking the heads during low
power idle mode, this drive delivers 5400 RPM-equivalent power
consumption in a 7200 RPM drive
Quiet
- In a notebook drive, silence is golden. WDs exclusive WhisperDrive
combines state-of-the-art seeking algorithms to yield one of the
quietest 2.5-inch hard drives on the market.
Reliable and rugged- WD's ShockGuard technology protects
the drive mechanics and platter surfaces from shocks during shipping
and handling and in daily operation.
- WD's SecurePark parks the recording heads off the disk
surface during spin up, spin down and when the drive is off. This
ensures the recording head never touches the disk surface resulting in
improved long term reliability due to less head wear and improved shock
tolerance.
Free-fall sensor - As an added layer of
protection, if the drive (or the system its in) is dropped while in
use, WDs free-fall sensor detects that the drive is falling and, in
less than 200 milliseconds, parks the head to help prevent damage and
data loss.
Tested for compatibility - We perform tests on
hundreds of systems and a multitude of platforms in our FIT Lab and
Mobile Compatibility Lab to give WD customers confidence that our
drives will work in their systems.
