WD Black hard drives combine a high performance 7200 RPM spin speed, 16 MB cache and SATA 6 Gb/s interface for the ultimate in power computing for notebooks.

WD Black drives feature a dual processor and bigger, faster dynamic cache for maximum read and write speeds.

Twice the processing power to maximize performance.

Enhanced reliability features help protect the drive and the data stored on it.

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.

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.

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.
