When I noticed perris's topic about ReadyBoost I started researching some stuff that I didn't know about ReadyBoost. I came across another term "ReadyDrive". I didn't know that ReadyDrive was but now I do! Here's a quote describing what Windows ReadyDrive is: I don't have any H-HDD (Hybrid Hard Drive) so I can't really test this out, but I found an interesting article on WikiHow that explains how to set this up and it also has some great tips. If anyone with an H-HDD is interested in trying this out then follow the article at eHow: http://www.ehow.com/how_2056409_use-readydrive-windows-vista.html Be sure to report your results back here and tell us about your experience!
