I like that it's easy to use and get the job done. It's simple to configure and make sure your hard drive stays running smoothly. There isn't much to dislike about this product. The one thing I don't care for is how it reads data off my external hard drive. I had to switch over to a different hard drive just to keep up with how much data it was reading off of it. Make sure you're not using a small hard drive as well because it will take forever to read all of the data off of it. We have solved the problem of keeping our drives fast and smooth by going with Diskeeper. We've been able to keep our hard drives running smoothly which has reduced the amount of downtime we've had in the past.
