Hello Josephur, Link Removed to Windows 7 Forums,
It actually depends on how much RAM you're running on your system.
If you're running 6Gb's of RAM or higher, then using ReadyBoost can actually slow it down, you also have to remember that USB devices are limited to a 2.0 bandwidth.
ReadyBoost has to encrypt everything because it's assuming removable media, whereas the hybrid solution has no such constraint.
I had 3Gb's RAM running Win 7 w/Patriot Razzo 8Gb's for ReadyBoost and it ran pretty fast, then I upgraded my RAM to 6Gb's leaving ReadyBoost on and I actually noticed a slowing on some programs, I removed the ReadyBoost and the speed returned and maybe a little faster, it also took me a while to figure it might be the flash...
