WD Black UltraSlim Hybrid Hard Drive

WD Black UltraSlim Solid State Hybrid Drives (SSHD) introduces high performance NAND flash SSD technology to the huge storage capabilities of traditional HDD storage uniting both to enhance the computing experience. A single WD Black UltraSlim SSHD Drive provides an optimized, all-in-one solution which synergizes SSD like performance, and massive HDD storage capacity in a single device. Power users such as digital artists, photographers, and gamers will welcome WD Black UltraSlim SSHD's ultra fast read and write speeds when it comes to their large creative and multimedia files. Utilizing an advanced set of algorithms, WD Black UltraSlim SSHDs track data usage, prioritizing frequently used data for fast access in the solid state portion of the device, adapting, learning and optimizing as new applications and command requests change over time. These advanced algorithms reside in the SSHD firmware, enabling it to make intelligent determinations of which data to store in NAND flash memory, without any influence from the host or related storage device drivers. By pairing SSD like performance with massive hard drive capacity, WD has created an intelligent hybrid drive that truly offers the best of both worlds. The WD Black UltraSlim SSHD hybrid drive is self contained in a traditional HDD form factor, and installs as easily as any traditional hard drive without special drivers or downloads required. WD Black UltraSlim SSHDs are compatible with most typical computer configurations, including PC and Mac.

  • For Gamers - WD Black UltraSlim Solid State Hybrid Drives offer the perfect storage solution for your gaming rig. WD Black UltraSlim SSHD 2.5-inch Hard Drives are purpose built and tested to ensure they can handle the high performance tasks you need. With up to 500GB of capacity, you get the space you need for your game’s downloadable content and large cache sizes for fast load times
  • Professional Performance - WD Black UltraSlim Solid State Hybrid Drive is built by fusing two world-class storage devices together into one dual drive to create the ultimate experience for notebooks and all-in-one PCs. Boot up faster to your operating system with the speed of SSD at your fingertips. WD Black Solid State Hybrid Drives features innovative 16GB NAND flash with remarkable power efficiency that is poised to redefine what is possible in the storage industry.
  • Industry Leading Warranty - WD Black UltraSlim Solid State Hybrid Drive are tested under more strenuous conditions over a longer period when compared to our standard hard drives. This comprehensive testing ensures an overall quality benchmark for a stable, high performance storage solution backed by an industry leading 5 year limited warranty.
  • 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 non-operational shock tolerance.
  • Rock-solid Mechanical Architecture - Twice the processing power to maximize performance.
  • 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.
  • 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.
  • 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.
  • Dynamic Cache - WD’s dynamic caching algorithm improves performance in real time by optimizing cache allocation between reads and writes. For example, if there’s an overwhelming percentage of read traffic as opposed to write traffic, the drive automatically allocates more cache for read data, which reduces congestion and improves overall drive performance.
  • Dual Processor - Twice the processing power to maximize performance.
  • 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 to help prevent damage and data loss.
  • Quiet - In a notebook drive, silence is golden. WD’s exclusive WhisperDrive combines state-of-the-art seeking algorithms to yield one of the quietest 2.5-inch hard drives on the market.
