storing data from ADXL345 with high data rate on sd card and FFT

-

hello,

i wondering possible on arduino (uno/mega) log data adxl 345 3200hz data rate on sd card , make fft in same time.
i think there might problem limited memory in microcontroler. there way overcome problem ? possible other device (for example rasppery pi)?

that normal arduino boards.
the arduino due lot faster, due still normal arduino without operating system, memory managment or file system.
the raspberry pi should able that, or perhaps can connect sensor computer kind of interface.
