As hard drive sizes continue to balloon, we are constantly bombarded with the one and singular question that guides our choice when it comes to the storage in our systems: Do we want a hard drive that has incredibly fast performance, or incredibly cavernous storage space? Though you can almost get that with the many 640GB 2-platter models that dot the landscape, true performance comes with drives like the VelociRaptor or any of the solid state drives out there. Western Digital is hoping to break that trend with their “Black Edition” Caviar hard drives.
