I don't bother doing this anymore. I do have a second drive for large files (I'm into photography) but everything else I have including the OS fits easily on a 1TB SSD. I haven't had one fail yet and can't remember the last time I had to reinstall Windows. And everything is backed up locally as well as to the cloud. If I had to wipe one of my machines, it is easy to restore the data to where it belongs.
