Have you ever wished you could put a SSD or 2nd HDD in your notebook, because you are feeling that the boot times and data access becomes more and more slowly or you have realized that you have far too much data to fit on your 1st regular HDD inside your notebook? By putting an IB-AC649 in your optical bay, you can add a SSD or second hard drive to your computer. Adding a solid state drive to your system can make it significantly faster, from decimating the boot times to speeding up application launch and data access or storing all of your large files on a 2nd regular hard drive.
