If you needed more proof that solid-state drives are the future of computer storage, today, Western Digital, one of the largest traditional hard disk drives manufacturers has jumped with both feet into the market. Although the company already listed a SiliconDrive SSD in its portfolio, following the acquisition of SiliconSystems last year, the new Intel's significantly faster X25-M G2 160GB on the other hand can be had for $429, while OCZ's Vertex Turbo 120GB are selling for as little as $360 these days.
