    I'm on a mid 2009 MacBook Pro Unibody with Snow Leopard. Here are the specs of my 1GB Flash drive plugged into my USB port. It's taking me about 6 min to transfer 700MB (approx 2Mbs/sec.). Anyone know any fixes for this issue?

    Have you tried the USB stick somewhere else, to see if it works faster on another machine?

    Most probably wit will be that the flash drive itself (not the USB connector on board) is very slow and may be one of the cheaper ones.

    Most USB flash drives I have seen, that report their write and read speeds on the packaging claim to have a maximum read speed of 8MB/s and a maximum write speed of 2-4MB/s.

    My USB flash drive seems to have an approximate write speed of 4MB/s on an early 2008 white MacBook.

    Here are the specs from System Profiler (I'm using 10.6.1 btw.):

    I'm fairly certain I have determined that the USB on my wife's Late 2007 MacBook is about 4x faster than my Mid 2009 MacBook Pro

    With the same USB flash drive?

    What OSs are on both MacBooks?
