Life hacker has a write up of the Five Best Disk Defragmenters. I have personally used Diskeeper for about 3-4 years and never had a problem. It will run in the background and you never notice it taking up CPU while you are working. My drives are always running at their optimum speeds. The reading and writing of large files is where you can really notice the difference. http://lifehacker.com/5348638/five-best-disk-defragmenters

I joined the program about 9 months ago when it first started on live.com. It has got so popular that they made a commercial for it. Here is the first Bing.com Cashback commercial.
Also I would like to note that you do not get any cash back until your account has $5 or more in it. They will send you a check or preferably by paypal. Paypal is pretty much getting paid within 24 hours. The cash back percentage changes almost daily it seems by some retailers. Over the 9 months that I have been in the program I have only seen 2 stores raise their cashback percentage. Most lower it every 3 months. There are occasional specials where they have a higher percentage for a 24 hour period. If you shop online at major retailers you have nothing to lose but cash back by joining the cash back program.
