I have both of these utility suites on 2 computers, and while both have good features, Norton's Speed disk isn't "speedy" in win xp, and jetfrag really doesn't seem to do any better.. If your going to spend $50-$60 on these software titles, I'd HIGHLY Recommend Diskeeper 7.0 it blows these other 2 away, and you can set the diskeeper to smart scheduling and never have to worry about defragging manually again. Go to www.executivesoftware.com and download the 30 day trial, you'll be hooked as i am!!!
