Fast WD, the first to introduce an 8 MB buffer, has advanced the caching algorithms of this new and improved family of hard drives, resulting in next-generation high performance. Cool 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 its class by lowering the drives power consumption through advanced design of electronics and firmware. Data Lifeguard Tools This software utility works with embedded Data Lifeguard features (including shock protection, an environmental protection system, and error detection and repair) to make hard drive installation, management, and diagnostics simple and worry-free.
