As per title, are there any benefits to be had using a USB flash drive for Ready Boost on a system with 4Gb RAM?
Obviously I have plenty of memory, but I wasn't sure if data was cached across reboots...
Superfetch addresses your question also.SuperFetch works like this: Vista will load anything it needs to load in memory first, and any applications you manually run will also be loaded into memory. Any memory left over is fair game to be used by SuperFetch as a cache of frequently used pages. Vista keeps track of what memory pages are frequently requested and what files they are tied to, and based on that data SuperFetch will populate as much free memory as it can with pages it believes you will need in the future. This data contains both frequency and temporal history, so not only how often but when you run these applications will influence what SuperFetch does at any given timehttp://www.anandtech.com/systems/showdoc.aspx?i=2917&p=4
