    Can one use a thumb drive for extra ram, if so, how? If I remember right, there was away of doing it with a P.C.

    I have a 21.5 Imac with 4 gigs of ram.

    Thanks,

    No, as a USB flash memory stick has slower memory than an actual RAM module. It is faster for the system to write to the internal HDD via swapping, than to actually use a slow USB stick.

    RAM is very fast, I don't know actual numbers, but it is a lot faster than 30MB/s, which you will get with USB and 10MB/s which you will get with most of USB thumb drives.

    The feature that is used in Windows is more for storing the swap files which come out of memory on a flash drive if I recall.

    Even though this is bit offtopic, 1066MHz DDR3 has transfer rate of 8533MB/s

    I know what you're meaning OP but can't remember the feature's name but anyway, it doesn't really speed up as spinnerlys stated due USB's limitations.
