Do you know how slow hard disks are at "random accessing"? They are very very very slow. What you see as 80MBps or so are just sequential transfer rates of large files. We need low access times than high transfer rates for our purpose.A typical 7200RPM drive will have access times around 12-15ms. A good flash drive will have it at 0.5ms. RAM will have it at 1ns or less.And remember this does not increase the amount of RAM installed in the system, NOT EVEN VIRTUAL MEMORY!!! This is just to supplement the pagefile on hard disk. The paging executable writes to both the flash drive and hard disk, and reads from the flash drive if the data is in it, if not goes to the hard disk, just as how the caching on the CPU works. (Cache is a duplication of data on RAM, not an addition)</blockquote>
