The 320 GB WD Caviar SE drives are perfect for desktop and enterprise storage applications where high performance and reliability are vital. WD's biggest drive yet, the 320 GB WD Caviar, is suitable for the most data-intensive environments. One drive can hold approximately 100 hours of high-resolution digital video, thousands of high-resolution images, and has plenty of space for the latest programs and games. Heat is a major contributor to hard drive wear, and cool drive operating temperatures help increase long-term drive reliability. WD achieves the lowest operating temperature of any hard drive in it's class by lowering the drives' power consumption through advanced design of electronics and firmware.WD minimizes WD Caviar noise to levels virtually below the threshold of human hearing with its WhisperDrive technology, which features a highly efficient power driver design. And to cut seek noise, Soft Seek technology streamlines read/write seeking algorithms, resulting in the drive operating more efficiently when accessing and writing data.
