When need to upgrade Windows 7 system hard drive?

"I suspect that the hard drive that contains my Windows 7 operating system is likely to fail soon. So now I am planning to upgrade Windows 7 system disk to a new hard drive in case that everything will get lost once the system disk completely fails someday. But I am not keen on reinstalling the OS onto the new disk, which requires much time and effort. So is there any way to transfer the current Windows 7 system hard drive to another one without reinstallation?"
