WDDA is intended to empower OEMs, system integrators, and IT professionals to better monitor and proactively manage supported storage devices to maintain optimal operation.

       Product Features

  • Hot Plug Support — SATA supports hot plugging (also known as “hot swapping”), the ability to swap out a failed hard drive without having to power down the system or reboot. This capability contributes to both data availability and serviceability without any associated downtime, making it a critical feature for extending SATA into enterprise applications.
  • Two-Dimensional Magnetic Recording (TDMR) Technology — New technology which places two read heads onto each arm, thus allowing data tracks to be squeezed closer together, enabling higher areal density required for a 18TB capacity at 9 disks.
  • CacheFlow Technology — WD’s unique, multi-generation caching algorithm evaluates the way data is read from and written to the drive and adapts “on-the-fly” to the optimum read and write caching methods. CacheFlow minimizes disk seek operations and overheads due to rotational latency. CacheFlow supports sequential and random write cache. With write cache and other CacheFlow features, the user can cache both read and write data. The cache can hold multiple writes and collectively write them to the hard disk.
  • IntelliSeek — Calculates optimum seek speeds to lower power consumption, noise, and vibration.
  • Dynamic Fly Height Control — Designed to compensate for head/media separation changes due to temperature and altitude. This feature adds video quality margins across temperature and altitude changes.
  • Triple Stage Actuator (TSA) — New technology for improved performance and accurate head and arm positioning, especially in multi-drive environments, for better performance.
  • Rotational Vibration Safeguard (RSV) — Maintains drive performance in high rotational vibration environments and multi-drive 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.
  • Energy-assisted PMR (ePMR) — ePMR is the first implementation of EAMR new technology. It utilizes a bias current applied to the head to enhance writability. This technology gives Western Digital HDDs areal density leadership while maintaining the reliability & performance needed for data center workloads.
  • Pre-emptive Wear Leveling (PWL) — This WD feature provides a solution for protecting the recording media against mechanical wear. In cases where the drive is so busy with incoming commands that it is forced to stay in a same cylinder position for a long time, the PWL control engine initiates forced seeks so that disk lubricant maintains an even distribution and does not become depleted. This feature ensures reliability for applications that perform a high incidence of read/write operations at the same physical location on the disk.
  • Fluid Dynamic Bearings (FDB) — Bearing design that incorporates a layer of high-viscosity lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional ball bearing technology, FDB designs provide increased non-operational shock resistance, speed control, and improved acoustics.
  • Premium Protection — Designed with tarnish-resistant components, this WD Purple drive offers premium protection in harsh environments where surveillance systems may be installed.
  • Power Management — The drive supports the ATA and SATA power management command set, allowing the host to reduce the power consumption of the drive by issuing a variety of power management commands.
