Where should I discuss SD/MMC FAT issues?

[JD123]

100 8 byte recordings per second? That's only 800 bytes... I said 600KB per second, as in, 614,400 bytes per second, 6,144,000 bits per second.
But again...it was a parallel operation.

Now are you talking 100 8 bytes recordings...
or 100 512 byte (sector) recordings

Yes, I messed up. See my edit.

That should be quite reachable. The real issue is reading the PWM outputs from the accelerometers and an airspeed pressure sensor. My co-worker on this project wants to read the PWM as filtered analog resolved from a 1ms PWM frame rate. I'm arguing that I can get everything done and more in the 16.66ms that we have at 60 recordings per second. Also, using the CCP and MUX'ing the inputs I can get rock solid data with a 5000 FS range. On a +/-10G accelerometer that will be .4mG resolution - well enough for what we are doing.
