With SATA and PATA interfaces, and  
cache sizes up to 32 MB, this series  
of drives offers a full range of  
performance features.  
WD Caviar Blue drives are available  
in capacities from 80 GB to 1 TB  
because you can never have too  
much storage space.  
Calculates optimum seek speeds to  
lower power consumption, noise  
and vibration.  
Instantaneously protects the hard  
drive against damage from bumps  
and vibrations while it is running.  
This technology enables WD Caviar

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.  
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.

Family and business computing.  
Desktop / Consumer RAID Environments - WD Caviar Blue Hard Drives are tested and recommended for use in consumer-type RAID applications (RAID-0 /  
RAID-1).  
- Business Critical RAID Environments – WD Caviar Blue Hard Drives are not recommended for and are not warranted for use in RAID environments utilizing Enterprise HBAs and/or  
expanders and in multi-bay chassis, as they are not designed for, nor tested in, these specific types of RAID applications. For all Business Critical RAID applications, please consider WDs  
Enterprise Hard Drives that are specifically designed with RAID-specific, time-limited error recovery (TLER), are tested extensively in 24x7 RAID applications, and include features like  
enhanced RAFF technology and thermal extended burn-in testing.

As used for storage capacity, one megabyte (MB) = one million bytes, one gigabyte (GB) = one billion bytes, and one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. As used for buffer or cache, one megabyte (MB) = 1,048,576 bytes. As used  
for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second, and gigabit per second (Gb/s) = one billion bits per second. Effective maximum SATA 3 Gb/s transfer rate calculated according to the Serial ATA specification published by the SATA-IO organization as of the
