Do a Read/Write test and use the fastest USB memory you have, that would make it as better as possible.better use four of 1GiB each than one of 4GiB if all have similar read/write/seek specs. Use of multiply USB 2.0 memories (assuming all have same seek time and speeds) is much better than using just only one of similar speed.ReadyBoost can read files faster form USB memory than form your actual HDD.Now things clear, ReadyBoost gain is only possible when: or use a Sata to CompactFlash / SD / etc adapter and use it for pagefile. better use a 4GiB Pagefile on a second Sata HDD. with ReadyBoost enabled such cache goes onto USB, leaving more RAM free.
What is readyboost for windows 7 free#
ReadyBoost is used for Read DATA when applications load files, are executed, etc.īut, if you do not have enought Free RAM for all apps loaded, then it can be a 'gain' because Windows tends to use a portion of RAM for such cache.
It has nothing to do with how much RAM is in use.
When ReadyBoost can gain? Easy: when HDD is slower than USB memory used.
Some USB sticks are very slow, some very good (and also very expensive) HDDs have a seek time of less than 1ms, for that ones, ReadyBoost can not gain anything, since the HDD is faster than any other.
