connecting BS to mass storage devices

I need to get serial input (from a GPS), process it and output it to
some kind of mass storage device such as a flash card or memory
stick. Processing serial input is well covered in this and other
fora but the storage part of it has been more difficult to find. I'd
love pointers to projects and hw dedicated to this.

The standard memory modules available are far too small since I'd
like to collect att fairly close intervals over a long time.
My idea is to log my own (full scale) glider flying, 5-7 hours of
collecting at , say, 5 second intervals.

TIA
Richard Soderberg

PS
I know there are commercial devices available such as the
Volkslogger doing this but hey, whats the fun in that?

    I need the same thing!! But I need huge amounts (I
    was looking into one of those 1 gig cards). This is
    to store digital photos of experiments (and other
    data) that will be flying about the international
    space station, and also the space shuttle. I've
    already sent a couple of emails to this group but I've
    never seen any response. If you figure this out let
    me know (and if I get it done, I'll drop you a line!)

    I need a very similar thing!

    I need to store 10hours of data, sample rate: 1 per second. Storing
    the $GPRMC sentence, it will take about 3.5MB of space.

    If anyone has any ideas, I will be most grateful.

    Best Regards

    Ashfaq

    Last year a guy by the name of Barry designed a interesting IDE interface
    (he used a compact flash card) with the stamp and eventualy ported it to the
    PIC.

    I don't know if Barry still checks the list but his page about how to do it
    and source code is still up, it might be worth a look...

    I interfaced a flashcard to a Javelin, using only 2 PCF8574 chips.
    A picture of that board is at
    http://groups.yahoo.com/group/synop/files/javelin%20stamp/Serial-CF%20board/
    Serial-CF.jpg
    Access to the flashcard is, due to I2C bus, slow at best: about 6.3 seconds
    per sector (512 bytes).
    For my logging purposes that is fast enough. I guess a basic stamp could be
    used but you must
    then also supply some additional (eeprom?) memory if you want to store
    complete sectors
    for fast(er) access. That particular board has a socket for an I2C eeprom.
