Product Benefits
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 drive’s power 
consumption through advanced design of electronics and firmware.
