Hello,

I have a Teensy 3.6 and a SanDisk Ultra 64GB microSD card. If I have 16 analog inputs sampled at 10,000 samples per second per channel (160,000 samples per second total) at 12-bit, should I be worried about loosing data when it is being written from RAM to the microSD? Is there anyway to maximize this write speed? Thanks in advance for any help.

All SD cards have variable latency while the card's built-in controller is busy. It can be up to about 0.1 or even 0.2 seconds on some cards. You must be able to buffer the incoming data in RAM during the card's worst latency.
