Windows ReadyBoost
The following are requirements for USB flash devices enhanced for
ReadyBoost: • USB flash drives themselves and the host controllers they are inserted into must both use the USB 2.0 standard. • USB flash drives must have at least 230 MB of free space. Flash Performance Flash storage devices must meet minimum performance requirements to support ReadyBoost, including 2.5 MB/s throughput for random 4K reads and 1.75 MB/s for random 512 K writes. Higher performance requirements must be met for the device to be designated as “enhanced for ReadyBoost”: 5 MB/s for random 4K reads and 3 MB/s for randmon 512 K writes. Microsoft recommends that users use devices enhanced for ReadyBoost (from "Windows PC Accellerators") "Bert" wrote in message ... Is there a certain size or speed that my flash drive needs to be to take advantage of ReadyBoost? |

You may also want to have a look at Grant Gibson's 'ReadyBoost Compatibility List' (http://www.grantgibson.co.uk/misc/readyboost/). I can't say how up to date it is, but there are listings for over 1,000 flash drives on there.

I would like to add that for now, ready boost is only designed for 1 flash
drive up to 4gb. They plan to increase this after further testing and design work. "Bert" wrote: Is there a certain size or speed that my flash drive needs to be to take advantage of ReadyBoost? |

Actually, it is limited to 4GB on a flash drive of arbitrary size. I use a
16GB Xporter. "SkyKnites" wrote in message ... I would like to add that for now, ready boost is only designed for 1 flash drive up to 4gb.
