USB Flash Drive Memory

When I insert my new 2GB Crucial USB flash drive in the slot, I choose
ReadyBoost. But a dialog box appears saying "This device does not have the
required performance characteristics for use in speeding up your system."

Does anyone know why I'm getting that message? What am I missing?

Thanks so much.

Actually, the error message is quite clear, and answers your question.


Is the flash drive you tried designed to work with ReadyBoost?

"To use Windows ReadyBoost, PCs must be preinstalled with Windows
Vista^(TM) and have access to a non-volatile flash memory buffer with at
least 1GB of storage capacity. The flash memory buffer must also meet
the requirements for random reads and random writes specified in the
Windows Vista Logo "Storage-0009 WLP" specification:
.. 5 MB/sec throughput for random 4k reads across the entire device
.. 3 MB/sec throughput for random 512k writes across the entire device"

"Q. What does it mean to be "Enhanced for Windows ReadyBoost^(TM)?
A. The phrase "Enhanced for Windows ReadyBoost" will be used to market
flash devices that are large enough and fast enough to consistently work
with Windows ReadyBoost. A drive that is Enhanced for Windows
ReadyBoost must be at least 512MB and must have random read and random
write speeds of 5MB/sec and 3MB/sec, respectively."

Thank you Bruce. You answered my question. My flash drive is brand new and is
2gb so it meets the minimum size, but I don't see anywhere where the package
says anything about it's characteristics except for size. Info such as
"random read and random write speeds" are no where to be found.

I'll look for that data on my next flash drive.
