MPU6050 and GPS fast logging using SDfat LowLatencyLogger

hi,

i new arduino community. want built fast motorbike gps/gyro/accel loggeur.

i want log acceleration/gyro data coming mpu6050.
i have gps shield outputs nmea messages @ 5hz
the mpu ouputs data 100hz rate. based on interrupt : isr raises flag each time mpu6050 has data available.

i tried simple logging schemes record gps , mpu6050 data on sd card, seems to slow , fifo buffer in mpu6050 gets filled rapidly.

i want use lowlatency example of sdfatlib supposed faster. code looks complicated me.

do think 1 fast enough?
the lowlatencylogger reads data @ reagular time interval (500hz) not exaclly fitted purpose. need record data when made available mpu6050 , gps.
which way should modify code work purpose.

thanks help!
