Id would be a great improvement if eboostr could prioritize witch caches to use, if there are many aviable. there should be no limitation of maximum supported caches or it should be so high, that everything is possible. I have 6 caches, but eboostr is using only 4 of them in an unpractical way: all hard disks, some usb, but no ram. I´ve had to exclude two drives and put them to vista ready boost. This is the only way I´ve got my ram cache to work. eboostr should use always the best cache. Does eboostr internally decide according to drive type where what type of data goes or are all devices handled equally? Does eboostr react to the safe remove function of windows? Why couldn´t the cache on External USB hard drives be encrypted?
