Want a bigger hard drive for your laptop, but you don’t want to sacrifice anything in performance? It seems that Samsung is pushing the envelope just a little further with the newly revealed Spinpoint MP4. This 2.5-inch hard drive sounds pretty sweet. For starters, it doesn’t stick to the conventional 5400rpm speed that you normally find in 2.5-inch notebook drives. Instead, it gives you 7200rpm of speed, putting it in line with the 3.5-inchers on the market. That means you’ll get at your data faster and more efficiently.
