A fresh clean install is the preferred method of installing the OS. Cloning software works reasonably well but sometimes glitches develop. This forum has had more than its fair share of questions about cloning issues. There is another benefit to a fresh clean install. Over a period of time Microsoft Windows will accumulate files that are no longer required. Windows does not do a very good job of deleting files, entries, and settings that are no longer required or needed.
If you still wish to use Paragon Migrate you can purchase and download it direct from the company. It isn't obvious until you click on the buy now icon.
I normally recommend Samsung solid state drives. They perform exceptionally well and have a proven track record. The Samsung 840 EVO is the number one best selling ssd in the world. Recently Samsung released the 850 Pro which is their new flagship model. In addition Samsung announced that an 850 EVO model will be released in the near future. Crucial, SanDisk, and Intel ssd's are also worth considering.
I maintain the ssd database listed in a sticky at the very top of this forum section. Here is the link:
