Has anyone had good (or bad) experiences enabling Ready Boost?

I have a few questions:

- What happens if you have enabled Ready Boost and you decide to unplug your USB memory? Will this cause havoc to your system?

- What is the minimum amount of memory you should use to see a meaningful difference?

- Are there certain read/write speeds you need to have (i.e. will this work on a SD card? will this work with a Seagate FreeAgent USB external hard drive?)

Thanks

Have a read - I've found that on systems with 1GB or memory or less, USB and fast SD cards do make a difference, but when my boxes have 2GB or more it seems to matter very little that readyboost is enabled.

It's basicly the same results. No real improvement.

How can you tell the difference? I have 1gb base, added a 512mb usb and it seems to run the same....if not slower at times?

Hmm...that was on my old machine. Let me post back since I have not tested on new.

I track load times on apps and file system reads/writes via perfmon, and file copies with a vbscript - I've noticed that a machine with 1GB of RAM or less (especially 512MB) seems to perform noticeably better in these tests than boxes with 2GB or more (1.5GB seems to depend a lot on hardware - some machines benefit, and some do not).
