    Is it safe to assume that a usb 3.0 flash drive is Ready Boost ready?


    As in title, is it safe to assume that a usb 3.0 flash drive is Ready Boost ready? I'm not finding any that actually say they are. This question assumes that the device will be plugged into a 3.0 port.

    I plugged my SanDisk 32GB USB 3.0 Thumb drive [noted by the blue insert] into my front USB 3.0 port, right-clicked the icon in File Explorer, click Properties then clicked the ReadyBoost tab, see that I can use it for ReadyBoost up to 4094MB or about 4GB. I could make the size less but not more. Where I'd see more use would be on Notebooks with the SDHC card port and 4GB or less physical RAM, mainly because the SDHC card doesn't protrude very far and less damage if bumped. Same for card readers on Desktops.

    Coincidentally, that is the model I was looking at. Looks like I have my answer. Thanks.

    It's not a safe assumption, none of my USB key drives Kingston 4 GB, 32 GB(USB 3) ones can be used with ReadyBoost.
