I’ve had my laptop for about five years now and it’s served me well. In that time, I had never re-installed Windows and it was starting to show. A bit buggy and too many crashes.
Rather than backing up and wiping, I purchased a solid state hard drive and installed a fresh operating system. What a transformation! Windows 7 now boots up in seven seconds and the computer is soooo fast now.
SSHD’s aren’t real cheap yet but if you want decent upgrade on speed then this can be a great way to go.
