Re: Readyboost will not work
USB 2,0 is sufficient, however speeds vary among "card Readers" - following
may be informative:
"Windows Vista runs a quick performance test to see if the device meets
minimum standards required for ReadyBoost. Those standards are:
a.. 2.5 MB/sec throughout for 4 KB random reads
b.. 1.75 MB/sec throughout for 512 KB random writes
These results must be consistent across the entire device....
also "...If the drive fails several tests, you can look up the specific
performance results for yourself. Open Event Viewer (Eventvwr.msc) and click
the Applications And Services Logs category in the console tree on the left.
Under this heading, click Microsoft, Windows, and ReadyBoost. Under this
latter heading, select Operational. The log entries in the center pane
include performance test results for both successful and unsuccessful
attempts...."
