With up to SATA 6 Gb/s interface and  
32 MB cache, next generation  
10,000 RPM WD VelociRaptor drives 
are up to 15% faster than the award-
winning previous generation (HLFS 
models). 

WD VelociRaptor SATA drives are 
available in capacities up to 600 GB, 
double the capacity of the previous 
generation (HLFS models). 

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. 

The 2.5-inch WD VelociRaptor is 
enclosed in a backplane-ready 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.  

Consumes less idle power and uses 
similar active power as the previous 
generation WD VelociRaptor, while 
offering double the capacity and higher 
performance.

Optimizes operation and performance 
when the drives are used in vibration-
prone, multi-drive chassis. 

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. 

In addition to being ROHS compliant, 
this generation of WD VelociRaptor is 
also a halogen-free design.
