WD Caviar Black 2TB & VelociRaptor 600GB
 

The Western Digital Caviar Black 2TB and VelociRaptor 600GB are two of the fastest SATA hard drives money can buy. HDD performance almost always comes at an acoustic price, but are these drives quieter than the predecessors, and do their speed/capacity/acoustics compete well against an SSD plus low cost high capacity HDD of similar cost?
