Passing heretofore unknown levels of speed, Lexar's newest addition to their memory card stable reaches the impressive 1000x milestone. The Lexar Professional 1000x will come in 16GB ($169.99), 32GB ($299.99), 64GB ($529.99), and 128GB ($899.99) sizes, and the company is promising "minimum guaranteed sustained read speed of 150MB per second" — which should be enough for even the largest of files.
