Lightning Fast – With state-of-the-art SATA II 300 MB/s transfer rates and 16 MB of cache, these drives push the boundaries of performance for their class.
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, 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
back planes.
FlexPower – connector technology that accepts power from both industry-standard and new SATA power supplies.
