I'm debating between spending $10-15 for a 150x 2gb SD card versus $20-25 dollars for a 233x 2 gb CF card for use with readyboost in Vista. Anyone have any thoughts about how much speed difference it would make? Thanks in advance.
I don't think it would matter much, because you really won't see much of a difference with ReadyBoost anyway, unless this is a system with less than 1 GB of memory. You don't say how much system memory you have, but chances are, you'd be better off either saving your money, or spending it on actual RAM.
I have 3gb of RAM so upgrading that isn't really feasable... but from what I've read, once Readyboost "learns" your useage patterns there can be some benefit. The minimal cost seems worth even modest speed increase.
Maybe I'm naive, but it seems that everyone who's tried readyboost for a short period of time doesn't see any benefit... the people who stick with it do seem to see an increase.
Now it sounds like you are confusing SuperFetch and ReadyBoost. You have 3 GB of memory, so you really don't need to waste anytime on ReadyBoost. SuperFetch will learn your usage patterns overtime.
$10-15 sounds like a very reasonable amount of money to spend and experiment to learn for yourself. I would love to hear from someone who's actually tested it for more than a few minutes, or read about it on a site somewhere.
I would think that making the index of your page file available quicker is going to benefit you no matter how much RAM you have. Thing is, if you have <1GB of RAM, you're going to page more than with 2GB of RAM, so it would be more noticeable with less memory. The more RAM you have, the more diminishing the return is because you don't need to swap to the page file as often.
I say buy the cheap one, run some tests and see if you notice it. It would be even better if you could test it on someone else who didn't know what you did. That way you can't imagine that it worked or didn't work!
