Customer Reviews

"My first impression is that this is the best version yet. Intelliwrite + Automatic Defragging take care of it all. Statistics show that IntelliWrite on my machine eliminates (or prevents) 90% or more of fragmentation."

— Steve Ringwald

"Since the installation of Diskeeper, the process has run flawlessly in the background, maintaining a 48% read/write improvement. It continues to maintain 90% prevented fragmentation by the magical IntelliWrite technology. This is quite impressive to see."

— David Cruz

Press Reviews
