WD Scorpio Blue Mobile Hard Drives

WD Scorpio Blue 2.5-inch SATA and PATA hard drives offer solid performance, ultra quiet operation and low power use for portable digital devices of all kinds. Pick the drive that suits your needs with the confidence in knowing that all WD Scorpio Blue drives are built to the highest standards of quality and reliability.

  • Massive Capacity - Storage capacity for 2.5-inch form factor drives with standard 9.5mm height has arrived at a realm once thought to be impossible - up to 2 TB - giving you all the capacity you need to keep your photos, music and files right there on your notebook.
  • Low Power Consumption - State-of-the-art seeking algorithms and advanced power management features ensure low power consumption and long battery life.
  • Ultra Cool and Quiet - In a notebook drive, silence is golden. WD’s exclusive WhisperDrive technology delivers one of the quietest 2.5-inch hard drives on the market.
  • StableTrac - Motor shaft affixed to the baseplate and top cover stabilizes platters for accurate tracking during read and write operations, yielding higher drive data throughput in harsh shock and vibration environments. Supporting the top cover with the shaft also increases robustness to pinch forces.
  • Dual Actuator Technology - A head positioning system with two actuators that improves positional accuracy over the data track(s).
  • 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.
  • Designed for Various Applications - WD Scorpio Blue has a portfolio of drives to satisfy all your portable computing needs. These drives are available in multiple z-heights including the 9.5mm industry standard, 7mm for use in thin notebooks and compatible with mainstream systems, and 12.5mm primarily for external enclosures.
  • WD Quality - Built to the highest standards of quality and reliability, these drives offer the features and capacity ideal for your everyday computing needs.
  • Reliable - 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 non-operational shock tolerance.
  • Rugged - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks.
  • 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 our customers confidence that our drives will work in their systems.
  • Advanced Format (AF) - Technology adopted by WD and other drive manufacturers to increase media format efficiencies, thus enabling larger drive capacities. (PVT models only)
