Question

I Have Windows Vista 64Bit Edition with 4GB XMS Corsair 800Mhz Ram will I see Performance increase using a 4GB USB Flash Drive & Readyboots and where could I purchase such a Readyboost USB Flash Drive of 4Gbs.

Answer 1

Not in the least ... not unless the usage of 4GB of RAM you already have peaks which is very unlikely.

There is some confusion about what Ready Boost does ... it DOES NOT add accessable ram to a PC. It just uses the ram in the flash drive for quick caching ... not anywhere near the same as true ram ....
.... it's just a quick alternative to hard disk caching.

"The flash memory device serves as an additional memory cache—that is, memory that the computer can access much more quickly than it can access data on the hard disk drive."

"I'm the Program Manager in the Microsoft Windows Client Performance group and own the ReadyBoost feature. I wanted to give some offical answers based on the excellent questions and discussions that I've seen in this blog, to date. Also, I'll be using this as a starting point for the official ReadyBoost FAQ.

Overall, as many posters have pointed out, the feature is designed to improve small random I/O for people who lack the expansion slots, money, and or technical expertise to add additional RAM. As y’all know, adding RAM is still the best way to relieve memory pressure.

Your very powerful PC won't see much of a difference ... if any.
