Unlike desktop PCs, you can't just add a second internal drive when you run out of space. The Corsair SSD and Hard Disk Drive Cloning Kit makes it easy for you to swap out your old drive for a larger one. Just attach your new SSD or hard drive to your notebook's USB port using the included cable, run the software, and then replace the old drive with your new one. The USB interface has a transfer rate that's about 4.5 times faster than USB 2.0. If you have a newer system with a USB 3.0 interface, the included USB 3.0 cable will allow you to take advantage of its superior performance. Using an older system? No problem! The cable is backward compatible with USB 2.0 ports.
