Product Range Features (Actual Product Features May Differ - Zaps)

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. 

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. 

The worst thing that can happen during a rendering process is losing data due to power fluctuation or power failure. The new generation of WD Black hard drives is equipped with Corruption Protection Technology (CPT), which helps to protect and limit the potential problem of data loss during power failure or power loss to the hard drive. Overall, Corruption Protection Technology can save you time and money on your project.
