Quit Safari, open Terminal (in Applications » Utilities), and enter this command:
defaults write com.apple.Safari DebugSnapshotsUpdatePolicy -int 2
Relaunch Safari, and it will no longer create snapshots of pages you visit.
[robg adds: I tested this, and it works. However, to really take advantage of it, you'll also want to delete the existing snapshots from your drive. The easy way is to use Safari -> Reset Safari, and leave only 'Remove all webpage preview images' checked, then click Reset.
If you delete all the existing previews and implement this hint, you'll see a generic placeholder for each page on the Top Sites screen. To get your previews back, quit Safari, and run this command in Terminal: defaults delete com.apple.Safari DebugSnapshotsUpdatePolicy. You won't see new previews until you visit each site on the Top Sites at least once.]
