I am using a readyboost capable flash drive, which has improved performance.
Got me to thinking, if I got a large enough flash drive, could I use that
drive as my swap drive and would that improve performance as well?
 
Basically, that is what ReadyBoost is doing. It's caching part of your swap
file onto the flash drive. But, after you go with so high, there is a point
of diminishing returns. I've used a 1 GB and a 4 GB flash drive. No
difference in ReadyBoost performance.
 
Most of the articles that study Readyboost points out that more ram is
desireable. If you're getting a noticble boost from readyboost,t hen you
might want to consider getting more system ram. I think one article noted
that 4GB is the largest supported readyboost drive.

On to your question, I don't think you're allowed to make a flash drive you
pagefile, I thought I had trouble with it, when I tried, just for the heck
of it. Plus Flash drives are really good at small 4k reads and large
sequtial reads are better on the hard drive. There was a Microsoft article
on it somewhere.

Here's a pretty good article that does some benchmarks, this always shows
how real ram give s the best performance over readyboost.

I found readyboost actually caused hiccups in frame rate as the device was
accessed.

Could it be because I was using a SD card in a reader? It came up as being
suitable for RB to use.

It's because it is way slower than RAM.
