Cool-running, superior performance, and industry-leading reliability make 
these drives the perfect hard drives for desktop, business, and consumer 
electronics storage — ideal for high-performance family computing such 
as photo editing, multimedia functions, and business applications such as 
spreadsheets and databases.
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.
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.
The WD Promise
WD understands the importance of the information you save to your hard 
drive and we are committed to protecting that data with exceptionally 
reliable products, advanced data protection technology, and superior 
customer support. No one does more to safeguard your data than WD.
