I’m just a blogger; have written about Readyboost; but never investigated it’s performance. I found an article today from PC World who took a closer look. Basically, it blows.
“What is Readyboost you ask?” well it’s a feature of Vista that allows flash memory (like USB Sticks) to be used as additional RAM to boost PC performance.
PC World took that claim and put it to the bench. First off, Microsoft indicates that only the best performing flash drives should be used, (3.5MBs per/sec reads and 2.5MBs per/sec writes) so although some web sites claim “use any extra flash drive for Readyboost,” that claim is a bunch of BS.
Using the best performing drives from Kingston, Lexar and Ridata it was concluded the Readyboost did improve performance, but only by 4 to 6%. So unless you had a stop watch - BFD! My Vista upgrade is going to wait.
For more details, here’s the original article link.
