Best set up for high speed DAQ?

I’m interested in measuring acceleration up to 10gs but at a high DAQ rate, as high as possible I think but would really like 1000Hz min. Can you recommend Sparkfun components for doing this? I’d like to save it to SD Card, but I think I could first save it to a buffer in memory during DAQ then save it to SD card when measurement is finished, as I only need to record for < 2 seconds.

Thanks.

The data sheet parameter you should look at is “output data rate”. 1 kHz is typically the maximum ODR.

This one, set to the +/- 24g range should be fine: https://www.sparkfun.com/products/10345

For data transfer, SPI is faster than I2C, but it is not uncommon to have problems with a uSD card sharing the SPI bus.
