As both drives are almost similar. With SATA and PATA interfaces, cache sizes ranging from 2 MB to 16 MB, WD Caviar Blue drives offer a full range of performance features. Pick the drive that suits your needs with the confidence in knowing that all WD Caviar Blue drives are built to the highest standards of quality and reliability. The WD Raptor has evolved! PC enthusiasts' favorite 10,000 RPM SATA drive is now faster than ever. WD VelociRaptor is 3.5-inch SATA Hard Drives with 300 GB, SATA 3 Gb/s, 16 MB Cache, 10,000 RPM. Anyways, i am defining both the drives with their features and specification here:-

Features of WD Caviar Blue drive :

Interface : PATA - Enhanced integrated drive electronics (PATA), 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.
Cache - WD Caviar Blue is available in 2 MB, 8 MB, and 16 MB cache sizes. Bigger cache memory yields faster performance.
Capacity - We offer drives ranging from 40 GB to 750 GB. Pick the biggest capacity your budget will allow. You can never have too much storage space.

Reliability - We understand the importance of your data, and we are committed to protecting that data with exceptionally reliable products, advanced data protection technology and superior customer support.
Cool - Keeping the drive cool enhances reliability. WD continues to develop new and innovative ways to keep drives cool while they are operating.
Quiet - The technology that Tom's Hardware Guide called "very fast and nearly silent" is used throughout this family of drives. Our WhisperDrive technology minimizes noise to levels near the threshold of human hearing. To cut seek noise, SoftSeek technology streamlines read/write seeking algorithms, resulting in more efficient operation.
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.
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.

Features of WD VelociRaptor

Killer speed - Built on the performance bloodlines of WD Raptor, these 10,000 RPM drives, with SATA 3 Gb/s interface, and 16 MB cache deliver mind-bending performance. Not only are they 35 percent faster than the previous generation WD Raptor drives, but they also beat out all other competitors in the field.
Rock-solid reliability - Designed and manufactured to mission-critical enterprise-class standards to provide enterprise reliability in high duty cycle environments. With 1.4 million hours MTBF, these drives have the highest available reliability rating on a high capacity SATA drive.
Double the capacity - State-of-the-art technology packs twice the capacity per disk compared to its older brother WD Raptor resulting in 300 GB of high-performance storage space in this enterprise-class 2.5-inch drive.
IcePack mounting frame - The 2.5-inch WD VelociRaptor is enclosed in a 3.5-inch enterprise-class mounting frame with a built-in heat sink that keeps this powerful little drive extra cool when installed in high-performance desktop chassis.
Rotary Acceleration Feed Forward (RAFF) - Optimizes operation and performance when the drives are used in vibration-prone, multi-drive chassis.
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.
