High Speed Large File Transfer via Ethernet

Anyone know if 's possible to read data from an SD Card fast enough with a STAMP or PROP to be able to send it over Wired Ethernet at true Ethernet speeds? Looking to transfer 200 meg files from SD Cards to PC and need to go faster than UART speeds.

    For sure not.

    Why not just use a 5 dollar SD card reader on your PC?

    By the way, what is "true Ethernet speed"? 10Mbits per second, a 100? More ?

    Welcome to the forum.

    The Propeller will do 3Mbaud asynchronous serial transfers, and faster synchronous serial transfers. You might look at Tachyon Forth for an ethernet interface support.

    BS2 is limited to 19200baud asynchrounous serial, and I'm not sure about synchronous serial. But it has only 32 bytes of RAM available for buffer.

    Thanks - If the propeller can do 3MBaud that's what I'm looking for. Then I can get that across both Ethernet or fast Ethernet. I'll start looking at the propeller some now.
    Thanks again
