I just bought a new SSD (Crucial M500 120 GB). First time SSD user. Anyway I'm not one of those dudes who feels it necessary to re-install an OS on a regularly basis. It's not one of my fun projects as it takes considerable time getting things back to my preferences. I'd rather not have to do it if it isn't REALLY necessary. I had the OS (Windows 7) on one of my HDDs that was split into 2 partitions. The partition that the OS was on was only 100 GB. I wanted to clone this partition to the new SSD thus not having to re-install the OS from scratch. Started searching around and found Paragon Migrate OS to SSD. Looked to be just what the doctor ordered. Bought it and installed it. Instructions couldn't be easier. Hooked up the SSD, fired up the program and it found my SSD, gave instructions what to do. Since my partition was smaller than the SSD, it copied the whole partition over so I didn't have to leave anything out. If the SSD is smaller than the source drive, you can eliminate what you want to make it fit. After the copy process, it told me to reboot and go into BIOS to set primary boot drive to the SSD. Did that and it booted to Windows on the SSD, no muss no fuss. All that was left to do was to delete the previous install of Windows 7. This was a nice handy program for me. It's pretty much a one use product but it was sure worth the $20 I paid for it. Saved me a lot of time and work.
