      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.
  • 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.
  • Dual Stage Actuator Technology — A head positioning system with dual-stage actuators that improves positioning accuracy over the data track(s). The primary stage provides course displacement; the secondary stage uses piezo electric motion to fine tune the head positioning to a higher degree of precision.
  • Femto Slider — These drives incorporate the femto slider form factor in which the read/write head is mounted on the small, lightweight femto slider which allows the head to move more quickly from track to track on the disk.
  • 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.
  • 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.
