Vista - ReadyBoost and High-end Systems

I'm running Windows Vista Ultimate (with Service Pack 1) on a fairly new
desktop system. I have 4 GB of RAM and I'm running a quad core Intel
processor (3 GHz) with a Western Digital Raptor 10,000 rpm hard drive.

I already know that I have a fairly fast system, but I'm wondering if
Vista's ReadyBoost might be able to speed up the system even more?

I have a 4 GB jump drive (USB) that I rarely use. I have plugged it into
one of the USB ports and have turned on the ReadyBoost option (to use the
full 4 GB). Thus far, I'm not really seeing too much of an increase in
overall speed. But I could be in correct about this. My perceptions may be
off.

My question is: with more advanced desktop and laptop systems, does
ReadyBoost provide any additional speed/performance advantages?

Thanks!

It provides some boost but it would be almost imperceptible because with 4GB
of ram you are not hammering the page file like you would with 2GB and
because your system is already so fast that change is hard to detect.

I takes a week or two of daily reboots to see the benefit to boot times due
to the assistance ReadyBoost provides to super fetch. Other then that you
may not notice the benefit to page file retrievals provided by the
ReadyBoost page file cache function.

Many thanks for the replies!

I will definitely see if the speed improves over an extended period of time.
It's only been a short while since I employed the jump drive in this
ReadyBoost scenario.
