Thanks for your more detailed reply, your first post seemed very
dismissive of the problem by just saying add more RAM as that isnt the
problem in case.

With the X41 (slower processor and less RAM than the Z60m), the SD
card makes a visible improvement.

The Z60m has massive spike in CPU when ReadyBoost is enabled on the SD
card...it has a 2Ghz processor, 2GB of RAM and a very good graphics
card (by laptop standards) so why should the CPU overload of 80-100%
when the SD card is added even f the system is capable of running
Vista without the SD card.

The validity of the SD card is debatable, I just want to know why
ReadyBoost would cause a CPU overload?

Thanks.
