Western Digital VelociRaptor is an amazingly fast hard disk drive. Targeted at the blade server and enthusiast markets, this Serial ATA hard disk drive not only delivers incredibly fast seek times and throughput, it also does it in a compact 2.5" form factor. Western Digital offers three versions of the VelociRaptor - BLFS, HLFS and GLFS.
The choice of models available made us wonder if there is any performance difference between the different models, so we decided to test it out. We had earlier reviewed the BLFS model but Chai bought a HLFS model so we thought it was a great opportunity to compare the performance of the two models.
