WESTERN DIGITAL VelociRaptor 600GB 10,000RPM 6.0GB/s
This Hard Drive is made for speed. 6.0GB/s and 10,000 RPM make for a very fast platform for storing, accesing, and using data. It is what is really going to make you personal computer fast. It is useable in most cases, but it is not useable with all motherboards, which is what you need to even use it. This Hard Drive has a 32MB cache which is fairly large for a hard drive so that is another big plus. This Hard Drive is also not very cheap, it is listed for $250 on newegg.com. If your system is compatable with 6.0 GB/s HDD's then you are in the clear to use it, and if not, then you have some upgrading to do before you can use this hard drive.
