Cool-running, quiet operation, superior performance and industry-leading reliability make the WD Caviar SE drives the perfect hard drives for desktop and enterprise storage.

Product Benefits

Fast – WD, the first to introduce an 8 MB buffer, has advanced the caching algorithms of this new and improved Caviar family of hard drives, resulting in next-generation high performance – performance that beats all competing 8 MB-cache drives.

Cool Running – Cool drive operating temperatures help increase long-term drive reliability. WD achieves the lowest operating temperature of any hard drive in its class, including slower drives spinning at 5,400 RPM, by lowering power consumption through advanced electronics and firmware.

Ultra Quiet – WD minimizes 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..

SecureConnect™ – provides a 500 percent stronger cable-to-drive connection than first-generation SATA hard drives and cables. Also ensures backward compatibility with legacy SATA cables and backplanes.
