<b>NoTouch Ramp Load technology</b>
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.
<b>Easy upgrade</b>
Acronis True Image, available as a download on the WD Support website, enables you to copy all your data to a new drive so you don't have to reinstall your operating system to get all the benefits of a new drive.
<b>Dynamic Cache</b>
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.
