Vista - SONY MEMORY STICK VS READYBOOST

Hi, anyone has any idea about the problem of Sony memory stick with
readyboost?

I am using a Sony Vaio laptop, which comes with the memory stick reader
(Sony own products). When I try to set the memory stick being used as
readyboost, the system said failed to test it? Can anyone explain? I am
using Memory Stick Pro II, which is high speed, I am not sure whether it's
faster than USB II or no, but I think it's very fast.

thanks

Anthony

Look for a note from the manufacturer that the flash drive is
Windows ReadyBoost Compatible. Not all manufacturers list this
on their packaging.

If the flash drive is not labeled as compatible with Windows ReadyBoost,
check its specifications to see if it is capable of reading and writing
data fast enough. The speed requirements for Windows ReadyBoost are at
least 2.5 MB per second throughput for 4 kilobyte (KB) random reads and
1.75 MB per second throughput for 512 KB random writes.

Note:

A flash drive may appear to meet these requirements, but Windows Vista
still may not detect the device as ReadyBoost-compatible if its rated
speed measures sequential performance instead of random performance,
and if performance is not consistently fast across the entire flash drive.
