160GB Hard Driver

Today, I bought a new hard driver, WD1600JB-00GVA0, made by Western Digital. Price is good, almost same as 120GB Seagate Hard Driver. I paid $120.00, tax included.

This is Western Digital High-Performance level EIDE product.
It’s benefits:
Fast — WD, the first to introduce an 8 MB buffer, has advanced the caching algorithms of this new and improved Caviar family of hard drives, resulting in next-generation high performance – performance that matches the speed of most 16 MB cache drives.
Cool-running – 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 it’s class, including slower drives spinning at 5,400 RPM, by lowering the drives’ power consumption through advanced design of electronics and firmware.
Quiet – Today’s PCs, digital video recorders and gaming machines are increasingly operated in environments where noise is less tolerated. WD minimizes WD Caviar 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, resulting in the drive operating more efficiently when accessing and writing data.
Data Protection Enhancements
Data Lifeguard™ is an expanded set of data protection features that include shock protection, an environmental protection system, and embedded error detection and repair features that automatically find, isolate, and repair problem areas that may develop over the extended use of the hard drive. With these enhanced data reliability features, the drive can perform more accurate monitoring and error repair and deliver exceptional data security.
Data Lifeguard Tools™ is a set of software utilities that work in conjunction with the embedded Data Lifeguard features to make hard drive installation, drive management diagnostics, and repair simple and worry-free.
Shock Guard™ provides outstanding improvements in shock and vibration protection for WD Caviar SE drives. Shock Guard allows instantaneous data protection at high shock values to achieve leading shock specifications.
