WD Scorpio Black Exclusive Features IntelliSeek - IntelliSeek technology calculates optimum seek speeds to lower power consumption, noise and vibration. SecurePark -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. ShockGuard - WD's ShockGuard technology protects the drive mechanics and platter surfaces from shocks during shipping and handling and in daily operation. Free-fall Sensor -As an added layer of protection, if the drive (or the system it’s in) is dropped while in use, WD’s free-fall sensor detects that the drive is falling and, in less than 200 milliseconds, parks the head off the disks to help prevent damage and data loss. WhisperDrive - WD's exclusive WhisperDrive technology combines state-of-the-art seeking algorithms that result in one of the quietest 2.5-inch drives on the market. Pricing WD Scorpio Black hard drives will be available at select distributors and resellers. MSRP for the WD Scorpio Black hard drives are up to 6,350 THB (depending on capacity and features).
