Audio data sampling and logging on MKRZero


Let me make this simple, by using SD library, can the data logging speed to the on-board SD card of Arduino MRKZero be around 80KB/s? If not, can I use the SdFat library on MRKZero? What is the approximate max speed of the SD card writing data on MRKZero?

Since I just want to test some algorithms, out-of-box sample codes, if possible, are the best.

Thank you in advance
