WD Black Slim Solid State Hybrid Drives

Western Digital Black Slim WD10S21X Solid State Hybrid Drives (SSHD) combine a generous amount of NAND flash SSD technology and massive HDD storage capacity into a single drive. The best combination of SSD and HDD to produce a hybrid that can increase overall system performance – resulting in quicker system boots, faster application loads, and improved responsiveness when compared to traditional hard drives. Low power consumption and Quiet operation is the next big thing in ultra fast performance storage. Introducing WD Black Slim Solid State Hybrid hard drive. The WD Black Slim Solid State Hybrid hard drive is a completely new approach in a compromised solid state and hybrid storage market. Finally you can have the speed of an SSD that you want and the capacity of a hard drive that you need in your notebook or all-in-one PC.

  • Best of Both Worlds - 1TB Capacity, 16MB Cache Buffer Size + 8GB MLC NAND Flash Memory built-in a 2.5" HDD for ultra performance to burst your Laptop/MacBook or PS3/PS4 Game Console performance to the highest levels. The WD Black Slim SSHD Drive is self contained in a traditional HDD form factor, and installs as easily as any traditional hard drive without special drivers or downloads.
  • Capacity and Speed - WD Black Slim SSHD Drives provide an optimized, all-in-one solution which synergizes SSD-like performance, and massive HDD storage capacity in a single device, and with 8GB of built-in NAND Flash, the WD Black Slim SSHD Drive performs at up to four to five times faster than traditional 5400 RPM Hard Drive for blazing fast performance.
  • For Gamers - WD Black Slim SSHD Drives offer the perfect storage solution for your gaming rig. WD Black Slim SSHD Drives are purpose built and tested to ensure they can handle the high performance tasks you need. With up to 1TB of capacity, you get the space you need for your game’s downloadable content and large cache sizes for fast load times. A gaming rig equipped with WD Black Slim SSHD Drive can deliver faster game loads, auto saves, and can reduce lag between levels when compared to traditional hard drives.
  • Professional Performance - WD Black Slim SSHD 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. Utilizing an advanced set of algorithms, WD Black Slim SSHD Drives track data usage and prioritizing frequently used data for fast access in the solid state portion of the device, learning and optimizing as new applications and command requests change over time.
  • Industry Leading Warranty - WD Black Slim SSHD Drives 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 technology 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. The WD Black Slimn SSHD Drives are performance tested for use in PCs, high-performance workstations and gaming 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 drives on the market.
