When ReadyBoost was first introduced it was limited to 2GB. Unless MS has
changed the way Vista uses ReadyBoost, or I misunderstood its use, I think
it is misleading to call it RAM since Vista has to read the data there back
into system RAM to use it just like it does with a normal hard drive cache.
As to 32 vs. 64 bit.... check with your vendors before you upgrade to Win 7.
If they do or will support 64 bit, you may want to reconsider.

Don,
My computer recognizes the SDHC as the 8 GB claimed; but only 4 GB was
allocated to ram usage. You're right that I have no idea of the speed
of this micro-SD card which is in a SD-adaptor; but the ReadyBoost
recommends and only allowed 4 GB. I haven't seen any speed improvement;
but I'm hoping that I'll later see faster page refreshes etc. when I do
some web surfing later. I'm using the 32-bit VISTA OS. Do you know if
the 64-bit VISTA or Windows 7 OS would permit more of the SD capacity to
be used than 4 GB. I'll probably be upgrading to 32-bit Windows 7
eventually, since I got burned at work with the 64-bit Windows XP when
venders would not update their drivers. But the advantages of 64-bit OS
is still alluring. Of course, with a 64-bit OS, I guess one could just
add more core ram; But I don't think I have any free slots
unfortunately, which is why this ReadyBoost memory has my attention
right now. I was just wondering.
I've got some 2/4/8 GB USB memory drives. I might try them later if I
can free up a USB connection to see if I can go beyond the 4 GB.
Wouldn't this be great if it would.
I haven't paid much attention to flashcard speed when it came to SD
cards (or the micro-SD) since I usually use them to transfer data or as
memory for my PDA/mobile phone where speed doesn't seem to be a factor.
The only place I've worried about speed is in my CF cards which I use in
my Nikon camera where it is important for rapid exposures. I guess I'
going to be looking at SD card speed now.
