View Full Version : windows ready boost

I was in windows 7 the other day and when I inserted a usb flash drive it asked me if I wanted to use it to speed up windows. My question is, wouldn't windows benefit more from a swap partition on the harddrive? Correct me if I'm wrong, but wouldn't essentially swap over usb be REALLY slow?

Readyboost is not swap, it's cache. You're right, swap over USB would be too slow. I think cache over USB would barely be faster than fetching the data off the hard drive anyway.

Readyboost was more use in the early days of Vista, when a lot of computers barely fit the minimum requirements and didn't have enough RAM left over for cache after running the operating system. Windows 7 has similar system requirements but today's computer have much more RAM than the early Vista machines.
