Faster Data logging with Arduino Giga — using USB or a Micro SD or there’s a better way?

[pancham_bhatt]

Hi, I just received Giga board for my project and need support with the following query:
What is the faster method for logging sensor data—using USB or a Micro SD card via SPI or there’s a better way?
The project involves reading sensor data over I2C and capturing data from 8 ADC Pins.

How much data and how often does it need to be recorded? ALL SD card functions are blocking until completed, so does that have an effect on your project?
If consistent timing for recording is important, send the data to a program on your PC to do the logging.
If integrity of the recording is important, then develop a message checking protocol for data sent to the PC.
