Western Digital Caviar Blue WD6400AAKS 640GB 7.2K SATA Hard Drive - New Pull OEM
PATA - Enhanced integrated drive electronics (EIDE), also called Parallel ATA (PATA), hard drives have been the standard in the computer industry for more than 10 years.
SATA - Serial ATA (SATA) hard drives are quickly becoming the new standard. Motherboard manufacturers now include SATA inputs on their boards. Because of their considerably narrower cables, SATA hard drives provide increased airflow and less clutter and in the computer system compared to PATA drives.
The performance difference - PATA drives support data transfer rates up to 100MB/sec, and all WD Caviar Blue SATA drive support 3 Gb/s transfer rates.
Solid performance - With SATA and PATA interfaces, and cache sizes up to 32 MB, this series of drives offer a full range of performance features.
Ultra cool and quiet - Keeping the drive cool enhances reliability. WD continues to develop new and innovative ways to keep drives cool while they are operating which helps protect the drive and the data stored on it.
Capacity - We offer WD Caviar Blue drives with capacities from 80 GB to 1 TB because you can never have too much storage space.
NoTouch ramp load technology - The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. IntelliSeek - Calculates optimum seek speeds to lower power consumption, noise and vibration.
ShockGuard - Instantaneously protects the hard drive against damage from bumps and vibrations while it is running. This technology enables WD Caviar drives to achieve industry-leading shock specifications.
Compatible - We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab and Mobile Compatibility Lab to give our customers confidence that our drives will work in their systems.
