Gamers, if you are building an ultimate rig — having the fastest; besides the video card, processor and a big memory, try also having a fastest hard-drive for fast processing, booting, and loading time. The common mindset that I heard in some gamers and enthusiast, is having a SATA II but traditional hard-drive which runs either on 7200 rpm; lucky if they have a 10,000 rpm traditional hard-drive. Times like this, Solid-State drive is the name of the game and Intel is making its footstep again in this field. They introduce the 520 series that will definitely satisy your fast processing and application requirement.
The said Solid-State drive uses a NAND Flash technology which is more faster and less power-hungry compared to the traditional hard-drive that is available in the market. The other thing that I like about this one, it is a SATA III 6gbps Solid-State Hardrive which is very fast, robust, and very reliable.
Having this hardware part on your list will complete your ultimate desktop rig.
