So you recommend not to clone. Should I reinstall the OS on the SSD?
That is what I would do.
Update the SSD firmware. Then wipe the drive under the win 8 install, you might get a strange delay after the format while the drive TRIM functions are being called but Win 8 has pretty good knowledge about the quirks of setting up a SSD and should do a pretty good job. You will have much better results in the long run if you let the OS install its own files and let the new subsystems do their thing.
By the way, What clone software do you use?
