Western Digital WD400JD Caviar SE 40GB 7.2K 3.5" SATA Hard Drive - Refurbished OEM
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.
