Sensor MMA8451 and Hardware Choice

Goodmornig,

I have an hardware question.

I'm using the sensor mma8451 with a datarate of 800Hz and a Raspberry Pi 2B with a quad-core  CPU 900MHz and RAM 1GB. Could be enough right? So why I don't have 800 samples every second? (I have only 200 samples per second)

Is it a bus problem? Should I use the 2 bus in parallel on the same sensor?

 

Thank you in advance

Luigi
